How to get return value when BeginInvoke/Invoke is called in C#

Question

Answer 1

If you want a return value from you method, you shouldn't be using async version of the method, you should use .Invoke(...). Which is synchronous, that is it will execute your delegate, and won't return until it's complete. In your example as it is now, BeginInvoke will send the request to execute your delegate, and return right away. So there is nothing to return.
