C# Explicitly Removing Event Handlers

Question

I was wondering if setting an object to null will clean up any eventhandlers that are attached to the objects events...

e.g.

Button button = new Butt         


        

Answer 1

Summary: You need to explicitly unsubscribe when the event source/publisher is long-lived and the subscribers are not. If the event source out-lives the subscribers, all registered subscribers are kept "alive" by the event source (not collected by the GC) unless they unsubscribe (and remove the reference to themselves from the event publisher's notification list)

Also this is a duplicate of Is it necessary to explicitly remove event handlers in C# and has a good title n answer. So voting to close.
