Question

I have the following problem:

I got a class with ~100 static events and i want to set all those events to null (removing all delegates) when Disposing.
Can I do this using reflection? because otherwise it would be a lot to write and hard to keep in sync with changes.

I tried something like this:

foreach (EventInfo eventInfo in GetType().GetEvents(BindingFlags.Static | BindingFlags.Public))
     {
        // ?
     }

but i dont know how to set them null. I guess this is not workong with reflection, is their maybee another easy way?

The following ought to work:

   foreach (EventInfo eventInfo in GetType().GetEvents(BindingFlags.Static | BindingFlags.Public))
   {
      FieldInfo field = GetType().GetField(eventInfo.Name, BindingFlags.Static | BindingFlags.NonPublic);
      field.SetValue(null, null);             
   }

Provided that there are indeed backing fields for the events of course, otherwise there is no way to “set” them.
