C# Interview Question and Answers
1 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
2 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
3 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
4 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
5 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
6 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
7 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
8 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
9 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:
10 :-
11 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
12 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
13 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
14 :- What class is underneath the SortedList class?
A sorted HashTable
15 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
16 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
17 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
18 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
19 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
20 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
21 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
22 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.

Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
135 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:
136 :-
137 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
138 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
139 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
140 :- What class is underneath the SortedList class?
A sorted HashTable
141 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
142 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
143 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
144 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
145 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
146 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
147 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
148 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
149 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
150 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
151 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
152 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
153 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.

266 :- What class is underneath the SortedList class?
A sorted HashTable
267 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
268 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
269 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
270 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
271 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
272 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
273 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
274 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
275 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
276 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
277 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
278 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
279 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
280 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
281 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
282 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:

284 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
285 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.

First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
398 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
399 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
400 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
401 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
402 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
403 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
404 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
405 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
406 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
407 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
408 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:

410 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
411 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
412 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
413 :- What class is underneath the SortedList class?
A sorted HashTable
414 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
415 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
416 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.

529 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
530 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
531 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
532 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
533 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
534 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:
535 :-
536 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
537 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
538 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
539 :- What class is underneath the SortedList class?
A sorted HashTable
540 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
541 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
542 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
543 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
544 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
545 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
546 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
547 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
548 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
549 :- What are the different ways a method can be overloaded?

Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
660 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:
661 :-
662 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
663 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
664 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
665 :- What class is underneath the SortedList class?
A sorted HashTable
666 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
667 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
668 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
669 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
670 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
671 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
672 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
673 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
674 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
675 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
676 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
677 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }

791 :- What class is underneath the SortedList class?
A sorted HashTable
792 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
793 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
794 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
795 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
Use ToTitleCase method. System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase("dotnetfunda.com is a very good website"); The output will be "Dotnetfunda.Com Is A Very Good Website"
796 :- How to sort an array into descending order?
First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
797 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
798 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
799 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
800 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
801 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
802 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
803 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
804 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
805 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
806 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
807 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:

809 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
810 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.

First sort the array using Array.Sort and then use Array.Reverse Eg. int[] number = new int[] {6, 4, 7}; Array.Sort(number); // sort in ascending order foreach (int i in number) { lblMessage.Text += i + "
"; } // reverse ie descending order Array.Reverse(number); lblMessage.Text += "
"; foreach (int i in number) { lblMessage.Text += i + "
"; }
923 :- How to read entire stream contents?
If you have a stream object (any of the stream like StreamReader, MemoryStream, FileStream) and you want to show its content, write following code. // here theStream is the stream object while (myStream.Position != myStream.Length) { Console.WriteLine("{0:x2}", myStream.ReadByte()); }
924 :- Write a single line of code to read the entire content of the text file. User following code string strContent = System.IO.File.ReadAllText(Server.MapPath("~/MyTextFile.txt"));
925 :- Can you prevent your class from being inherited by another class?
Yes. The keyword “sealed” will prevent the class from being inherited.
926 :- Can you allow a class to be inherited, but prevent the method from being over-ridden?
Yes. Just leave the class public and make the method sealed.
927 :- What are the different ways a method can be overloaded?
Different parameter data types, different number of parameters, different order of parameters.
928 :- What is the use of CommandBehavior.CloseConnection?
We can use pass it with ExecuteReader method of Command object like reader = cmd.ExecuteReader(CommandBehavior.CloseConnection); This will make sure that when we are calling reader.Close() the associated connection object will also be closed.
929 :- How to declare a property in a class?
int m_PersonID = 0; public int PersonID { get { return m_PersonID; } set { m_PersonID = value; } }
930 :- How to declare a property in an Interface?
DateTime DateOfBirth { get;set;} int Age { get;set;} string FirstName { get;set;} As this is an Interface, so no implementation required only definition of properties are required. Implementation of these properties will be written into the class inherting this interface.
931 :- How to declare methods into an Interface void Calculate(); int Insert(string firstName, string lastName, int age); Interface doesn't contain implementation so methods implementation will be written into class inherting this interface.
932 :- How to load assembly from GAC?
Lets say you have to load the assembly from GAC on button click event then you should write following method. protected void btn_Click(object sender, EventArgs e) { AssemblyName asm = new AssemblyName("ClassLibrary1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=fbc28d9ca2fc8db5"); Assembly al = Assembly.Load(asm); Type t = al.GetType("ClassLibrary1.Class1"); MethodInfo m = t.GetMethod("Method1"); str = "reflection - " + (string)m.Invoke(null, null); MessageBox.Show(str); } For more visit http://www.infosysblogs.com/microsoft/2007/04/loading_multiple_versions_of_s.html
933 :- Difference Between dispose and finalize method?
Dispose is a method for realse from the memory for an object. For eg:
934 :-
935 :- What does the term immutable mean?
The data value may not be changed. Note: The variable value may be changed, but the original immutable data value was discarded and a new data value was created in memory.
936 :- What’s the difference between System.String and System.Text.StringBuilder classes?
System.String is immutable. System.StringBuilder was designed with the purpose of having a mutable string where a variety of operations can be performed.
937 :- Are private class-level variables inherited?
Yes, but they are not accessible. Although they are not visible or accessible via the class interface, they are inherited.
938 :- What class is underneath the SortedList class?
A sorted HashTable
939 :- What happens if you inherit multiple interfaces and they have conflicting method names?
It’s up to you to implement the method inside your own class, so implementation is left entirely up to you. This might cause a problem on a higher-level scale if similarly named methods from different interfaces expect different data, but as far as compiler cares you’re okay. To Do: Investigate
940 :- Types of Errors ?
Configuration Errors Parser Errors Compilation Errors Run-Time Errors
941 :- Difference between classes and structures?
A struct is a value type and a class is a reference type. When we instantiate a class, memory will be allocated on the heap and when struct gets initiated it gets memory on the stack. Classes can have explicit parameter less constructors. But structs dosn't have this. Classes support inheritance. No inheritance for structs. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Like classes, structures can implement interfaces.
942 :- How to convert a sentence into Title Case (Capitalize first character of every word)?
