Hello,

Can we declare delegates in the class? Can we declare delegates in interface
?

Warm Regards,

Bhuwan
 
Yes and no. The thing to remember about delegates is they are in themselves
classes that inherit from System.Delegate. Since nested classes are allowed
in classes you my declare a delegate in a class. For example the following
is legal:

public class MyClass
{
public delegate void MyDelegate();
}

To reference that delegate outside of MyClass you would write the following:

MyClass.MyDelegate myDel;

Since a delegate is a type that inherits from delegate you cannot declare a
delegate within an interface, because you cannot declare nested types in an
interface. That being said I tend to declare my delegates outside of a class
and inside a namespace, because like I said delegates really are just classes.
