Question

The requirement is that object A subscribes to B‘s event which carries int as an argument. I’ve done this in given manner:

public delegate void BackToBase(int i);
public event BackToBase BackToBaseEvent;

...
if (this.BackToBaseEvent != null)
    this.BackToBaseEvent(5);

But it seems to me there is a shorter way to do that. Is there?

Answer 1

You could marginally shorten this by using a generic delegate like EventHandler<T>:

public event EventHandler<int> BackToBaseEvent;

The null check is pretty important though.
