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 i开发者_高级运维deas?
This should work:
var fieldInfo = fooEventDispatcher.GetType().GetField(
"FooEvent", BindingFlags.Instance | BindingFlags.NonPublic);
var eventDelegate = fieldInfo.GetValue(fooEventDispatcher) as MulticastDelegate;
if (eventDelegate != null) // will be null if no subscribed event consumers
{
var delegates = eventDelegate.GetInvocationList();
}
Also you should use typeof(SomeFooClass)
instead of fooEventDispatcher.GetType()
if the type is already known at compile time (which I assume it is).
