The WeakEventManager.ListenerList<TEventArgs> type exposes the following members.

Public methodWeakEventManager.ListenerList<TEventArgs>()Initializes a new instance of the WeakEventManager.ListenerList<TEventArgs> class.
Public methodWeakEventManager.ListenerList<TEventArgs>(Int32)Initializes a new instance of the WeakEventManager.ListenerList<TEventArgs> class with the specified initial capacity.
Public propertyCountGets the number of items contained in the WeakEventManager.ListenerList. (Inherited from WeakEventManager.ListenerList.)
Public propertyIsEmptyGets a value that declares whether this WeakEventManager.ListenerList is empty. (Inherited from WeakEventManager.ListenerList.)
Public propertyItemGets or sets a specific listener item in the WeakEventManager.ListenerList . (Inherited from WeakEventManager.ListenerList.)
Public methodAddAdds a IWeakEventListener object to the WeakEventManager.ListenerList. (Inherited from WeakEventManager.ListenerList.)
Public methodAddHandlerAdds an event handler to the WeakEventManager.ListenerList. (Inherited from WeakEventManager.ListenerList.)
Public methodBeginUseDeclares the list to be in use. This prevents direct changes to the list during iterations of the list items. (Inherited from WeakEventManager.ListenerList.)
Public methodCloneCreates a modifiable clone of this WeakEventManager.ListenerList, making deep copies of the values. (Overrides WeakEventManager.ListenerList.Clone().)
Protected methodCopyToCopies the current WeakEventManager.ListenerList to the specified WeakEventManager.ListenerList (Inherited from WeakEventManager.ListenerList.)
Public methodDeliverEventDelivers the event being managed to each listener in the WeakEventManager.ListenerList<TEventArgs>. (Overrides WeakEventManager.ListenerList.DeliverEvent(Object, EventArgs, Type).)
Public methodEndUseUnlocks the locked state initiated by BeginUse. (Inherited from WeakEventManager.ListenerList.)
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
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.)
Public methodRemoveHandlerRemoves an event handler from the WeakEventManager.ListenerList. (Inherited from WeakEventManager.ListenerList.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
