Question

In C#, I could do something like this:

EventHandler handler = this.SomeEvent;

…which would allow me to, for example, do:

Delegate[] attachedHandlers = handler.GetInvocationList();

In VB.NET, I can’t seem to figure out how to do a similar thing.

This doesn’t work:

Dim handler As EventHandler = Me.SomeEvent

…due to the following error:

Public Event SomeEvent(sender As
Object, e As EventArgs)’ is an event,
and cannot be called directly. Use a
‘RaiseEvent’ statement to raise an
event.

But this doesn’t work either:

Dim handler As EventHandler = AddressOf Me.SomeEvent

…because:

‘AddressOf’ operand must be the name of a method (without parentheses).

So how can I actually get an EventHandler from an event in VB.NET? The only idea that’s immediately coming to mind is to use reflection, but that seems pretty ridiculous.

Answer 1

   Private Event MyEvent()
   Private delegates() As System.Delegate = MyEventEvent.GetInvocationList()
