Removing event handlers

Question

Is this:

Button.Click -= new EventHandler(Button_Click); 

the same as this:

Button.Click -= Button_Click; 

I ask because to me it seems that the former is removing a new reference to a method, and the latter one is removing a method itself. But then again, maybe the new EventHandler part is implicit in the += or -= overload in case the programmer doesn't explicitly assign it like that?

In case it is different how about

Button.Click -= new EventHandler(Button_Click); 

VS

Button.Click -= Button_Click; 

Thanks.

Answer 1

It is the same. The second is merely syntactic sugar for the first, and equality comparison is overloaded appropriately for delegate types:

Two delegates of the same type with the same targets, methods, and invocation lists are considered equal.
