You can use Action<T> for a delegate that takes a variable and returns void.

But note that you can also just declare your own delegate types if you want to. Action<T>, for example, is just

public delegate void Action<T>(T obj)

I don't know but is it necesary to usea delegate will the purpose not solved by only making the return type as void – Meetu Choudhary Jun 10 '09 at 05:37
You can't specify void (or Void) as a type argument. – Jon Skeet Jun 10 '09 at 05:41
but the question is about return type not for the agruments – Meetu Choudhary Jun 10 '09 at 05:49

Will the Action<T> delegate work for you?

You may want:

Action<T> a = (t) => // your code here...
