C# event with custom arguments

Question

I want to have an event that takes an enum only as the argument. For example

public enum MyEvents{
   Event1
}

// how do I declare this to take enum MyEvent         


        

Answer 1

I might be late in the game, but how about:

public event Action EventTriggered = delegate { }; 

private void Trigger(MyEvent e) 
{ 
     EventTriggered(e);
} 

Setting the event to an anonymous delegate avoids for me to check to see if the event isn't null.

I find this comes in handy when using MVVM, like when using ICommand.CanExecute Method.
