このコンストラクターは、既定の伝達と継承を指定します。 つまり、 InheritanceFlags.None と PropagationFlags.None。

このコンストラクターは、NTAccount コンストラクターにidentityを渡し、新しく作成したNTAccount.NTAccount(String) オブジェクトをNTAccount コンストラクターに渡すことで、RegistryAccessRule(IdentityReference, RegistryRights, AccessControlType) オブジェクトを作成することと同じです。

パラメーター

例外

注釈

すべてのレジストリ キーはコンテナーであるため、レジストリ キーに意味のある継承フラグは InheritanceFlags.ContainerInherit フラグだけです。 このフラグが指定されていない場合、伝達フラグは無視され、即時キーのみが影響を受けます。 フラグが存在する場合は、次の表に示すように規則が反映されます。 このテーブルでは、子サブキー CS と孫サブキー GS を持つサブキー S があることを前提としています。 つまり、孫サブキーのパスは S\CS\GS です。

孫サブキーのパターンは、孫サブキーに含まれるすべてのサブキーを管理します。

たとえば、ContainerInheritにinheritanceFlags フラグを指定し、InheritOnlyにpropagationFlags伝達フラグを指定した場合、この規則は即時サブキーには適用されませんが、すべての直接の子サブキーと、そのサブキーに含まれるすべてのサブキーに適用されます。

次のコード例では、継承と伝達を使用したアクセス規則を示します。 この例では、 RegistrySecurity オブジェクトを作成し、 ContainerInherit フラグを持つ 2 つのルールを作成して追加します。 最初のルールには伝達フラグがなく、2 番目のルールには NoPropagateInherit と InheritOnlyがあります。

RegistrySecurity オブジェクトにルールが表示され、RegistrySecurity オブジェクトを使用してサブキーが作成されます。 プログラムは子サブキーと孫サブキーを作成し、各サブキーのルールを表示します。 最後に、プログラムはテスト キーを削除します。
