Events IN Interfaces...

[Milby7]

Hi there!

I have a very quick question... Can you declare an event to be part of an interface?? e.g.

public interface IMyInterface
{
public event MyEventHandler MyEvent;
}

Thanks!!

From MSDN: "The static and public modifiers are not permitted on interface methods."

So you can write this

public interface IMyInterface
{
     event MyEventHandler MyEvent;
}

... and it works

There's an interesting reason for that. Since the purpose of an interface is to define a means of exposing functionality (and only that), scoping modifiers don't really apply: in effect, all the internals of an interface are public already. For example, it wouldn't make sense for an interface to specify a private method, since by definition it isn't exposed as a means of accessing functionality. To define it as public is superfluous.
