Dieser Konstruktor gibt die Standardweitergabe und Vererbung an. Das heißt, InheritanceFlags.None und PropagationFlags.None.

Dieser Konstruktor entspricht dem Erstellen eines NTAccount Objekts, indem er an den NTAccount.NTAccount(String) Konstruktor übergibt identity und das neu erstellte NTAccount Objekt an den RegistryAccessRule(IdentityReference, RegistryRights, AccessControlType) Konstruktor übergibt.

Ausnahmen

Hinweise

Alle Registrierungsschlüssel sind Container, daher ist das Flag das einzige Vererbungsflag, das InheritanceFlags.ContainerInherit für Registrierungsschlüssel von Bedeutung ist. Wenn dieses Flag nicht angegeben ist, werden die Weitergabeflags ignoriert, und nur der unmittelbare Schlüssel ist betroffen. Wenn das Flag vorhanden ist, wird die Regel wie in der folgenden Tabelle dargestellt weitergegeben. In der Tabelle wird davon ausgegangen, dass es einen Unterschlüssel S mit untergeordnetem Unterschlüssel CS und Enkelunterschlüssel GS gibt. Das heißt, der Pfad für den Enkelunterschlüssel lautet S\CS\GS.

Das Muster für den Enkelunterschlüssel steuert alle Unterschlüssel, die im Unterschlüssel "Enkelkind" enthalten sind.

Wenn beispielsweise das ContainerInherit Flag für inheritanceFlags angegeben und das InheritOnly Verteilungsflag für propagationFlagsangegeben ist, gilt diese Regel nicht für den unmittelbaren Unterschlüssel, sondern für alle unmittelbaren untergeordneten Unterschlüssel und für alle darin enthaltenen Unterschlüssel.

Beispiele

Im folgenden Codebeispiel werden Zugriffsregeln mit Vererbung und Weitergabe veranschaulicht. Im Beispiel wird ein RegistrySecurity -Objekt erstellt und dann zwei Regeln mit dem ContainerInherit Flag erstellt und hinzugefügt. Die erste Regel weist keine Weitergabeflags auf, während die zweite und InheritOnlyaufweistNoPropagateInherit.

Das Programm zeigt die Regeln im RegistrySecurity -Objekt an und verwendet das RegistrySecurity -Objekt dann, um einen Unterschlüssel zu erstellen. Das Programm erstellt einen untergeordneten Unterschlüssel und einen Enkelunterschlüssel und zeigt dann die Regeln für jeden Unterschlüssel an. Schließlich löscht das Programm die Testschlüssel.
