StrongNameIdentityPermission クラス

厳密な名前の ID アクセス許可を定義します。このクラスは継承できません。

[ComVisibleAttribute(true)] 
public ref class StrongNameIdentityPermission
 sealed : public CodeAccessPermission

J#

/** @attribute SerializableAttribute() */

解説

StrongNameIdentityPermission を使用して、呼び出し元のコードが特定の厳密に名前付けされたコード アセンブリ内にあるかどうかを確認することによって、バージョン管理と名前の保護を実現します。

厳密な名前 ID は、BLOB という暗号公開キーに基づいています。これは、オプションで固有のアセンブリの名前とバージョンを組み合わせることができます。このキーは一意の名前空間を定義しており、名前の定義はこのキーと対応する秘密キーによって署名されたアセンブリに存在する必要があるため、このキーによって名前が本物かどうかを厳密に検証できます。

厳密な名前キーの有効性は、必ずしも信頼関係またはキーに対して発行される証明書に依存しません。

メモ
StrongNameIdentityPermission に対するフル アクセス要求は、要求を満たす適切な証拠をスタック内のすべてのアセンブリが持っている場合に限り成功します。StrongNameIdentityPermissionAttribute を使用するリンク要求は、直前の呼び出し元が適切な証拠を持っている場合に限り成功します。

厳密な名前の詳細については、StrongName のトピックを参照してください。厳密な名前付きのアセンブリの詳細については、「厳密な名前付きアセンブリ」を参照してください。

StrongNameIdentityPermission クラスは、型のパブリック メンバにアクセスするための、厳密な名前の要件を定義する場合に使用します。StrongNameIdentityPermissionAttribute 属性を使用すると、厳密な名前の要件をアセンブリ レベルで定義できます。.NET Framework Version 2.0 では、InternalsVisibleToAttribute を使用して、アセンブリに含まれるパブリック以外のすべての型を、別のアセンブリに公開するように指定することもできます。詳細については、「フレンド アセンブリ (C# プログラミング ガイド)」を参照してください。

使用例

StrongNameIdentityPermission クラスの使用方法を示すコード例を次に示します。この例は、クラス ライブラリの形式になっており、StrongNameIdentityPermissionAttribute 属性と、呼び出し元を特定の厳密な名前で署名するように要求する StrongNameIdentityPermission の両方に適用されます。
