This is sort of a trick question. You can instantiate an instance of an Abstract class by using System.Activator.CreateInstance

No, you cannot, it thows exception "System.MemberAccessException: Cannot create an abstract class"

This is not working. Following is the code:

using System;

using System.Collections.Generic;

using System.Text;

namespace ConsoleApplication2

{

public abstract class sayhello

{

public void hello()

{

Console.WriteLine("hello");

}

}

class Program

{

static void Main(string[] args)

{

Object o=System.Activator.CreateInstance(typeof(sayhello));

((sayhello)o).hello();

}

}

}

Please clarify..

We can create an instance of an abstract class.

The below code is not working:

sayHello is an abstract class

Object o=System.Activator.CreateInstance(typeof(sayhello));
