RegistryPermission.GetPathList(RegistryPermissionAccess) メソッド

定義

名前空間:

System.Security.Permissions

アセンブリ:

System.Security.Permissions.dll

パッケージ:

System.Security.Permissions v9.0.0-rc.2.24473.5

ソース:

RegistryPermission.cs

指定した RegistryPermissionAccess を含むレジストリ変数すべてのパスを取得します。

public:
 System::String ^ GetPathList(System::Security::Permissions::RegistryPermissionAccess access);

public string GetPathList (System.Security.Permissions.RegistryPermissionAccess access);

member this.GetPathList : System.Security.Permissions.RegistryPermissionAccess -> string

Public Function GetPathList (access As RegistryPermissionAccess) As String

パラメーター

access

RegistryPermissionAccess

レジストリ変数アクセスの単一の型を表す RegistryPermissionAccess 値の 1 つです。

戻り値

String

指定した RegistryPermissionAccess を含むレジストリ変数の一覧 (セミコロン区切り)。

例外

ArgumentException

access が RegistryPermissionAccess の正しい値ではありません。

- または -

access が AllAccess で、レジストリ変数アクセスの 2 つ以上の型を表しているか、NoAccess で、レジストリ変数アクセスのどの型も表していません。

例

次のコード例は、 メソッドの使用方法を GetPathList 示しています。

// AddPathList adds access for the specified registry variables to the existing state of the permission.
// SetPathList sets new access for the specified registry variable names to the existing state of the permission.
// GetPathList gets paths for all registry variables with the specified RegistryPermissionAccess.

注釈

現在のアクセス許可の状態を取得するには、このメソッドを使用します。 このメソッドは、アクセスの種類ごとに個別に呼び出す必要があります。

注意

パラメーターは access 、 の値 RegistryPermissionAccessに制限されます。これは、単一の型のレジストリ変数アクセスを表します。 これらの値は、 Read、 Write、および です Create。 と を含NoAccessAllAccessめないように指定accessできる値。これは、単一の型のレジストリ変数アクセスを表しません。
