You can use Action delegates. This is much more elegantly then using data you will never need (I mean EventArgs).

Here you define events:

public event Action EventWithoutParams;
public event Action EventWithIntParam;

EventWithoutParams();
EventWithIntParam(123);

You can find all the information you need at Action or Action.

Either of these events can be initialised with a no-op delegate ... = delegate { }; so that you don't need to check for null before firing the event.
