Ejemplos

En el ejemplo de código siguiente se muestra EventWaitHandleRights el uso de valores al EventWaitHandleAccessRule crear y usar objetos.The following code example demonstrates the use of EventWaitHandleRights values when creating and using EventWaitHandleAccessRule objects. En el ejemplo se EventWaitHandleSecurity crea un objeto, se agregan reglas que permiten y deniegan distintos derechos para el usuario actual, y se muestra el par de reglas resultante.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. A continuación, el ejemplo permite nuevos derechos para el usuario actual y muestra el resultado, que muestra que los nuevos derechos se combinan con AccessControlType.Allow la regla existente.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

En este ejemplo no se adjunta el objeto de seguridad EventWaitHandle a un objeto EventWaitHandleSecurity; EventWaitHandle.GetAccessControl vea, método EventWaitHandle.SetAccessControly.This example does not attach the security object to an EventWaitHandle object; see EventWaitHandleSecurity, EventWaitHandle.GetAccessControl method, and EventWaitHandle.SetAccessControl.

Utilice la EventWaitHandleRights enumeración para especificar derechos de control de acceso EventWaitHandleAccessRule al crear objetos.Use the EventWaitHandleRights enumeration to specify access control rights when you create EventWaitHandleAccessRule objects. Para aplicar derechos de acceso a un evento del sistema con nombre EventWaitHandleAccessRule , agregue primero EventWaitHandleSecurity objetos a un objeto y EventWaitHandleSecurity , a continuación, adjunte el objeto EventWaitHandle.EventWaitHandle(Boolean, EventResetMode, String, Boolean, EventWaitHandleSecurity) al evento del EventWaitHandle.SetAccessControl sistema con nombre mediante el constructor o el método.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.

No se admite la seguridad en los objetos de sincronización para Windows 98 o Windows Millennium Edition.Security on synchronization objects is not supported for Windows 98 or Windows Millennium Edition.
