I have a big question that can probably be best elucidated via some code:
public class SomeClass
{
// This guy will raise an important event.
private EventSource _source = new EventSource();
public void AttachEventHandler()
{
// This guy will handle an important event...
BigEventListener listener = new BigEventListener();
_source.BigEvent += new EventHandler(listener.OnBigEvent);
//What happens to listener instance here?
//Will it be garbage collected?
}
}
So what happens after the method AttachEventHandler() is called?
I am assuming that the EventHandler delegate's reference to the OnBigEvent method
of the listener instance is a hard reference. In other words,even though listener is a
local instance and would normally go out of scope when AttachEventHandler ends,
that the listener instance is not collected because of the delegate reference. Is this
correct?
