No-op lambda

Question

I have an event on one of my classes that I want to attach a handler to. However, I don't need the handler to do anything, as I am just testing the behaviour of the class with handlers attached or not.

The event signature is as follows:

public event EventHandler<EventArgs> Foo; 

So I want to do something like:

myClass.Foo += (); 

However this isn't a valid lambda expression. What is the most succinct way to express this?

Answer 1

myClass.Foo += (s,e) => {}; 

or

myClass.Foo += delegate {};
