Esempi

Nell'esempio di codice riportato di seguito viene EventWaitHandleRights illustrato l'utilizzo dei valori EventWaitHandleAccessRule durante la creazione e l'utilizzo di oggetti.The following code example demonstrates the use of EventWaitHandleRights values when creating and using EventWaitHandleAccessRule objects. Nell'esempio viene creato EventWaitHandleSecurity un oggetto, vengono aggiunte regole che consentono e negano diversi diritti per l'utente corrente e viene visualizzata la coppia di regole risultante.The example creates an EventWaitHandleSecurity object, adds rules that allow and deny various rights for the current user, and displays the resulting pair of rules. Nell'esempio vengono quindi consentiti nuovi diritti per l'utente corrente e viene visualizzato il risultato, mostrando che i nuovi diritti vengono AccessControlType.Allow Uniti con la regola esistente.The example then allows new rights for the current user and displays the result, showing that the new rights are merged with the existing AccessControlType.Allow rule.

Nota

In questo esempio l'oggetto di sicurezza non viene collegato EventWaitHandle a un oggetto EventWaitHandleSecurity; EventWaitHandle.GetAccessControl vedere, metodo EventWaitHandle.SetAccessControle.This example does not attach the security object to an EventWaitHandle object; see EventWaitHandleSecurity, EventWaitHandle.GetAccessControl method, and EventWaitHandle.SetAccessControl.

Commenti

Utilizzare l' EventWaitHandleRights enumerazione per specificare i diritti di controllo di accesso EventWaitHandleAccessRule quando si creano oggetti.Use the EventWaitHandleRights enumeration to specify access control rights when you create EventWaitHandleAccessRule objects. Per applicare i diritti di accesso a un evento di sistema denominato EventWaitHandleAccessRule , aggiungere prima EventWaitHandleSecurity di tutto oggetti a un EventWaitHandleSecurity oggetto, quindi alleghi l'oggetto all' EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) evento di sistema EventWaitHandle.SetAccessControl denominato usando il costruttore o il metodo.To apply access rights to a named system event, first add EventWaitHandleAccessRule objects to an EventWaitHandleSecurity object, then attach the EventWaitHandleSecurity object to the named system event using the EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) constructor or the EventWaitHandle.SetAccessControl method.
