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
