Kommentarer

Om du vill vänta på en EventWaitHandle (genom att anropa WaitOneWaitAny - eller WaitAll -metoden) måste en användare ha EventWaitHandleRights.Synchronize åtkomst. Om du vill signalera en händelse genom att anropa Set metoden eller återställa den till det osignalade tillståndet genom att anropa Reset metoden måste en användare ha EventWaitHandleRights.Modify åtkomst. Om du vill signalera ett EventWaitHandle objekt och sedan vänta på det genom att anropa SignalAndWait metoden måste en användare ha Synchronize och Modify komma åt det.

Exempel

Följande kodexempel visar hur konstruktorn används för att skapa EventWaitHandleAccessRule objekt. Exemplet skapar ett EventWaitHandleSecurity objekt, lägger till regler som tillåter och nekar olika rättigheter för den aktuella användaren och visar det resulterande regelparet. Exemplet tillåter sedan nya rättigheter för den aktuella användaren och visar resultatet, vilket visar att de nya rättigheterna slås samman med den befintliga Allow regeln.

Den här konstruktorn motsvarar att skapa ett NTAccount objekt genom att skicka identity till NTAccount.NTAccount(String) konstruktorn och skicka det nyligen skapade NTAccount objektet till EventWaitHandleAccessRule(IdentityReference, EventWaitHandleRights, AccessControlType) konstruktorn.
