Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodPurgeRemoves all entries from the list where the underlying reference target is a null reference. (Inherited from WeakEventManager.ListenerList.)
Public methodRemoveRemoves the first occurrence of a listener item from the WeakEventManager.ListenerList. (Inherited from WeakEventManager.ListenerList.)
