Here is a version that works from outside of the class ...


       static void PrintListenners(object o, string _EventName)
       {
           Type t = o.GetType();
           FieldInfo[] fields = t.GetFields(BindingFlags.NonPublic |
BindingFlags.Instance);
           foreach (FieldInfo f in fields)
           {
               Console.WriteLine(f.Name + " " + f.ReflectedType.ToString());
           }
           FieldInfo fi = t.GetField(_EventName,
BindingFlags.NonPublic | BindingFlags.Instance);
           Delegate del = (Delegate)fi.GetValue(o);
           foreach (Delegate d in del.GetInvocationList())
           {
               Console.WriteLine("Method Name: {0}", d.Method);
               Console.WriteLine("Type Name: {0}", d.Target);
           }
       }


Cheers,

Greg

Subject: [ADVANCED-DOTNET] Determining if an event has been assigned a 
delegate...

Guys,

Do any of you know if it's possible to determine if an event for an object has 
been assigned a delegate?

Example:

Dim cb As New CheckBox()
cb.Name = "MyCheckBox"
AddHandler(cb.CheckChanged, AddressOf CheckChanged)

...

Public Sub CheckChanged(Object sender, EventArgs e) ...
End Sub

Is it possible to know if cb.CheckChanged has been assigned a handler or not?

Thanks,
Mike
