The virtual function is used to allow the subclasses to provide implementation for that  method using the keyword override.

class  base1
{
public void A()
{
Console.WriteLine("base1.A is called");
}
public virtual void virt()
{
Console.WriteLine("base1.virt is called");
}
}

we have abstarct class in c# which are working like virtual function.and if abstarct class containing all abstarct method thn that class will be equivalent to pure virtual function..........

User abstract modifier on method.
Class must also be marked as abstract.
An abstract method cannot have implementation.

As I know pure virtual doesn't exist in C# (it's C++ concept)
If you are using abstract class you cannot make instance of this class but you can implement functions.
