Understanding events and event handlers in C#

Question

I understand the purpose of events, especially within the context of creating user interfaces. I think this is the prototype for creating an event:

public vo         


        

Answer 1

publisher: where the events happen. Publisher should specify which delegate the class is using and generate necessary arguments, pass those arguments and itself to the delegate.

subscriber: where the response happen. Subscriber should specify methods to respond to events. These methods should take the same type of arguments as the delegate. Subscriber then add this method to publisher's delegate.

Therefore, when the event happen in publisher, delegate will receive some event arguments (data, etc), but publisher has no idea what will happen with all these data. Subscribers can create methods in their own class to respond to events in publisher's class, so that subscribers can respond to publisher's events.
