SecurityPermission.Flags プロパティ

セキュリティ アクセス許可フラグを取得または設定します。

Public Property Flags As SecurityPermissionFlag
[C#]
public SecurityPermissionFlag Flags {get; set;}
[C++]
public: __property SecurityPermissionFlag get_Flags();public: __property void set_Flags(SecurityPermissionFlag);
[JScript]
public function get Flags() : SecurityPermissionFlag;public function set Flags(SecurityPermissionFlag);

プロパティ値

SecurityPermissionFlag で定義される任意のアクセス許可ビットのビットごとの OR の組み合わせが表す現在のアクセス許可の状態。

例外

解説

それぞれのアクセス許可ビットは、この値に対して AND 演算を実行し、0 以外であることを確認することによって決定できます。
