SecurityPermission コンストラクタ (SecurityPermissionFlag)

フラグの初期設定状態を指定して、SecurityPermission クラスの新しいインスタンスを初期化します。

名前空間: System.Security.Permissions
アセンブリ: mscorlib (mscorlib.dll 内)

構文

'宣言
Public Sub New ( _
    flag As SecurityPermissionFlag _
)
'使用
Dim flag As SecurityPermissionFlag

Dim instance As New SecurityPermission(flag)

public SecurityPermission (
    SecurityPermissionFlag flag
)

public:
SecurityPermission (
    SecurityPermissionFlag flag
)

public SecurityPermission (
    SecurityPermissionFlag flag
)

public function SecurityPermission (
    flag : SecurityPermissionFlag
)

適用できません。

パラメータ

  • flag
    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アクセス許可の初期状態。

例外

例外の種類 条件

ArgumentException

flag パラメータが、SecurityPermissionFlag の有効値ではありません。

使用例

SecurityPermission コンストラクタを使用し、セキュリティ アクセス許可を要求するときに使われる SecurityPermission クラスのインスタンスを作成するコード例を次に示します。コード全体については、SecurityPermissionAttribute コンストラクタのトピックを参照してください。
