Using IDisposable to unsubscribe events

Question

I have a class that handles events from a WinForms control. Based on what the user is doing, I am deferencing one instance of the class and creating a new one to handle the

Answer 1

My personal vote would be to have an Unsubscribe method in order to remove the class from events. IDisposable is a pattern intended for deterministic release of unmanaged resources. In this case you not managing any unmanaged resources and therefore should not be implementing IDisposable.

IDisposable can be used to manage event subscriptions but probably shouldn't. For an example I point you to WPF. This is a library rife with events and event handlers. Yet virtually no class in WPF implements IDisposable. I would take that as an indication that events should be managed another way.
