Exempel

I följande kodexempel används AddAuditRule metoden för att lägga till en granskningsregel i en fil och använder RemoveAuditRule metoden för att ta bort granskningsregeln från filen. Du måste ange ett giltigt användar- eller gruppkonto för att kunna köra det här exemplet.

Kommentarer

Metoden RemoveAuditRule tar bort antingen alla matchande Deny granskningsregler eller alla matchande Allow granskningsregler från det aktuella FileSystemSecurity objektet. Du kan till exempel använda den här metoden för att ta bort alla Deny granskningsregler för en användare genom att skicka ett FileSystemAuditRule objekt som skapats med hjälp av Deny värdet, Failure värdet och ett användarkonto. När du gör detta RemoveAuditRule tar metoden bort alla nekande regler som anger Failure värdet eller Success värdet.
