WeakEventManager.ListenerList.IsEmpty Property

public:
 property bool IsEmpty { bool get(); };

public bool IsEmpty { get; }

member this.IsEmpty : bool

Public ReadOnly Property IsEmpty As Boolean

Property Value

true if the list is empty; otherwise, false.

Remarks

This method is equivalent to checking whether the Count is zero, and does not check whether any of the references in the list are now stale. If you want to assure that all references are still valid, call Purge just prior to checking the empty status of the list.
