Poznámky

Metoda RemoveAuditRule odebere buď všechna odpovídající Deny pravidla auditu, nebo všechna odpovídající Allow pravidla auditu z aktuálního FileSystemSecurity objektu. Tuto metodu můžete například použít k odebrání všech Deny pravidel auditu pro uživatele předáním FileSystemAuditRule objektu vytvořeného pomocí Deny hodnoty, Failure hodnoty a uživatelského účtu. Když to uděláte, RemoveAuditRule metoda odebere všechna pravidla zamítnutí, která určují Failure hodnotu nebo Success hodnotu.
