Silly delegate question

[Mark]

How many superdelegates does it take to screw in a lightbulb?

No... I was wondering if an instance of delegate stateful or can it be
reused?

For example you see a lot of (new AsyncCallback (method), param) it i/o
calls. If the delegate itself isn't carrying state, it seems like you could
have

static AsyncCallback myAsyncDelegate = new AsyncCallback (method);
....
AsyncOpofChoice.Beginxxx( myAsyncDelegate, param);

Thanks
Mark

It can certainly be effectively stateful, in that the target of a
delegate may change as the result of calling the delegate. However, if
you would be using the same target and the same action, there is indeed
no reason to create another instance each time.

Thanks Jon and Peter for your replies!

Hi Mark,

I agree with Jon and Peter. But I couldn't understand your real question
exactly.

If you haven't got the answer you want to this question, could you please
explain more about the question?

I look forward to your reply!

Hi Linda (and Jon and Peter)...

Yes, this was very helpful - especially Peter's clarification that it's as
stateful as the method you make a delegate of and the interactions it has. I
was wondering if there was any state kept in the delegate object itself; I
figured there probably wasn't but just wanted to be sure.

Thank you all for your responses.
