How can I get a list of the underlying delegates from an event using reflection?

First, GetInvocationList() won't work, because I want to be able to get to them from outside the class. I assume it will work with some reflection magic, and that's what I'm trying to figure out.

Here's what I have right now:

fooEventDispatcher.GetType().GetField("FooEvent", BindingFlags.Instance | BindingFlags.NonPublic);
var field = fieldInfo.GetValue(fooEventDispatcher);

I just don't know what to do with field. Any ideas?
