Pass an event as a parameter to a method [duplicate]

Answer 1

No, unfortunately not.

If you look at Reactive Extensions, that suffers from a similar problem. Three options they use (IIRC - it's been a while since I've looked):

• Pass in the corresponding EventInfo and call it with reflection
• Pass in the name of the event (and the target if necessary) and call it with reflection
• Pass in delegates for subscription and unsubscription

The call in the latter case would be something like:

SubscribeAndDoUnsubscribe(elements,
                          handler => e.Click += handler,
                          handler => e.Click -= handler);

and the declaration would be:

void SubscribeDoAndUnsubscribe(
        IEnumerable elements,
        Action> subscription,
        Action> unsubscription)
    where TEventArgs: EventArgs
