delegates and events

[Chris]

Hi,

is it possible to know what event-handlers are 'connected' to an event ?

(In the same style as you have access to the InvocationList with delegates.)

Thnx
Chris

Chris,
Seeing as an event is implemented in terms of a Delegate, yes you use
InvocationList to get the list of event-handlers.

The trick is getting the delegate for the event. Using a tool such as
ILDASM, you can see that the delegate is the name of the event with Event on
the end.

Public Class Chris

Public Event Changed As EventHandler

Public Sub GetHandlers
Dim list() As System.Delegate
list = me.ChangedEvent.GetInvocationList()
End Sub

End Class

Hope this helps
Jay
