Question

If I have an event like this:

public delegate void MyEventHandler(object sender, EventArgs e);
public event MyEventHandler MyEvent;

And adds an eventhandler like this:

MyEvent += MyEventHandlerMethod;

… is it then possible to register this somehow? In other words – is it possible to have something like:

MyEvent.OnSubscribe += MySubscriptionHandler;

Answer 1

Similar to auto-implemented properties, events are auto-implemented by default as well.

You can expand the declaration of an event as follows:

public event MyEventHandler MyEvent
{
    add
    {
        ...
    }
    remove
    {
        ...
    }
}

See, for example, How to: Use a Dictionary to Store Event Instances (C# Programming Guide)

See Events get a little overhaul in C# 4, Part I: Locks for how auto-implemented events differ between C# 3 and C# 4.
