c# - How do I get the subscribers of an event?

Question

I need to copy the subscribers of one event to another event. Can I get the subscribers of an event (like MyEvent[0] returning a delegate)?

If this is not possible I would use the add accessor to add the delegates to a list. Would that be the best solution?

Answer 1

C# events/delegates are multicast, so the delegate is itself a list. From within the class, to get individual callers, you can use:

if (field != null) 
{ 
    // or the event-name for field-like events
    // or your own event-type in place of EventHandler
    foreach(EventHandler subscriber in field.GetInvocationList())
    {
        // etc
    }
}

However, to assign all at once, just use += or direct assignment:

SomeType other = ...
other.SomeEvent += localEvent;
