What are you trying to accomplish functionally? You can't really do what you're describing from the 'outside', because the public functionality of an event is just what the compiler is telling you about: the ability to add or remove a handler. What the interal implementation is for that event is off limits to you - maybe the implementor is leveraging the default implementation for events, or maybe they've provided custom add/remove handler that are storing the delegate references being passed to them in a hashtable or other data structure. So being able to query whether anyone's registered for an event (and if so, how many) isn't part of the public functionality of an event. Obviously, any class you write that publishes events can also provide a property or method that provides that information. But it's not part of the natural event facilities, so you're not going to see it in the MSFT framework libs - or most others. -Mike Bear Canyon Consulting LLC http://www.bearcanyon.com http://www.pluralsight.com/mike =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
