このアクセス許可は、呼び出しコードが特定のゾーンからダウンロードされたかどうかを判断できます。ゾーンは、Microsoft Internet Explorer のオプションに従って構成され、Internet Explorer の IInternetSecurityManager および関連する API によって URL から割り当てられます。アクセス許可では、正確なゾーンの一致だけを定義します。つまり、URL は 1 つのゾーンだけに属することができます。
-
ローカル イントラネット ゾーン : ローカル イントラネット ゾーンは、会社のイントラネットにあるコンテンツで使用します。サーバーは、会社のファイアウォール内にあるため、イントラネットのコンテンツにはより高いレベルの信頼を割り当てます。
-
信頼されたサイト ゾーン : 信頼されたサイト ゾーンは、インターネット上の他のサイトよりも評判が高く信頼できると見なされた Web サイトにあるコンテンツで使用されます。このゾーンを使用して、固有なインターネット サイトにより高いレベルの信頼を割り当てることができます。これらの信頼されている Web サイトの URL は、ユーザーがこのゾーンに割り当てる必要があります。既定では、信頼されたサイト ゾーンのサイトは、インターネット ゾーンのサイトより信頼性は低くなります。このゾーンに属するサイトに、より高いレベルの信頼を付与する場合、ユーザーまたは会社はこのゾーンに付与する信頼のレベルを変更する必要があります。
-
インターネット ゾーン : インターネット ゾーンは、別のゾーンに属さないインターネット上の Web サイトで使用します。既定の設定では、これらのサイトからダウンロードされたコードのアクセス権は、ユーザーのコンピュータのリソースに対して最小限になります。他のゾーンに割り当てられていない Web サイトは、自動的にこのゾーンに割り当てられます。
-
制限付きサイト ゾーン : 制限付きサイト ゾーンは、ダウンロードした場合に問題が発生する可能性がある、または以前に発生したことがあるコンテンツを持つ Web サイトで使用します。このゾーンは、これらのサイトからダウンロードしたコードが、ユーザーのコンピュータで実行されることを禁止するために使用できます。これらの信頼されていない Web サイトは、ユーザーがこのゾーンに割り当てる必要があります。
-
ローカル コンピュータ ゾーン : ローカル コンピュータ ゾーンは、ユーザーのコンピュータに存在するコンテンツが使用する暗黙のゾーンです。ローカル システムに Internet Explorer がキャッシュしたコンテンツを除き、ユーザーのコンピュータにあるコンテンツは高い信頼レベルで処理されます。

.NET Framework Version 1.0 および 1.1 では、アクセス許可状態値 Unrestricted を ID アクセス許可に割り当てることはできません。.NET Framework Version 2.0 では、任意のアクセス許可状態値を ID アクセス許可に割り当てることができます。つまり、バージョン 2.0 では、ID アクセス許可の動作が、IUnrestrictedPermission インターフェイスを実装しているアクセス許可の動作と等しくなります。バージョン 2.0 のアプリケーションをバージョン 1.1 の CAS ポリシーで実行する方法については、「<legacyV1CASPolicy> 要素」を参照してください。 |

ZoneIdentityPermission コンストラクタ (PermissionState)
アセンブリ: mscorlib (mscorlib.dll 内)
構文
例外
解説
完全に制限した (None) アクセス許可または Unrestricted アクセス許可のいずれかを作成します。
メモ |
---|
.NET Framework Version 1.0 および 1.1 では、アクセス許可状態値 Unrestricted を ID アクセス許可に割り当てることはできません。.NET Framework Version 2.0 では、任意のアクセス許可状態値を ID アクセス許可に割り当てることができます。つまり、バージョン 2.0 では、ID アクセス許可の動作が、IUnrestrictedPermission インターフェイスを実装しているアクセス許可の動作と等しくなります。バージョン 2.0 のアプリケーションをバージョン 1.1 の CAS ポリシーで実行する方法については、「<legacyV1CASPolicy> 要素」を参照してください。 |
