WeakDelegates Sample

  • Article

This sample demonstrates the following:

  • Using the Micro Framework’s WeakDelegate class to notify the object of events. A WeakDelegate allows the object to have its memory reclaimed as long as the application has no other references to the object (forcing it to stay alive).
  • Defining an event that uses WeakDelegate objects to refer to the objects that have registered interest in the event.
  • Creating an object and registering it with an event supporting WeakDelegates.
  • How a strong reference to the object ensures that it receives notification when the event is raised.
  • How no strong references to the object allows a garbage collection to destroy the object. Consequently, the object will not receive any further notifications when the event is raised.
