WaitHandle.Dispose Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Releases all resources used by the current instance of the WaitHandle class.

Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)


Public Sub Dispose
public void Dispose()




Call Dispose when you are finished using the WaitHandle. The Dispose method leaves the WaitHandle in an unusable state. After calling Dispose, you must release all references to the WaitHandle so the garbage collector can reclaim the memory that the WaitHandle was occupying.


Always call Dispose before you release your last reference to the WaitHandle. Otherwise, the resources it is using will not be freed until the garbage collector calls the WaitHandle object's Finalize method.
