SecurityPermissionFlag 列挙体

セキュリティ アクセス許可オブジェクトのアクセス フラグを指定します。

この列挙体には、メンバ値のビットごとの組み合わせを可能にする FlagsAttribute 属性が含まれています。

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

メンバメンバ
 メンバ名説明
AllFlagsアクセス許可の無制限状態。 
Assertionこのコードのすべての呼び出し元に操作のために必要なアクセス許可があることをアサートする機能。 
BindingRedirectsアプリケーション構成ファイルで明示的にバインディング リダイレクトを実行するためのアクセス許可。これには、統合された .NET Framework アセンブリのリダイレクトだけでなく、.NET Framework の外で見つかったアセンブリのリダイレクトも含まれます。 
ControlAppDomainAppDomain を作成し、操作する機能。 
ControlDomainPolicyドメイン ポリシーを指定する機能。 
ControlEvidence証拠を提供する機能。これには、共通言語ランタイムが提供する証拠を変更する機能が含まれます。 

これは強力なアクセス許可であるため、信頼性の高いコードだけに付与するようにしてください。

ControlPolicyポリシーを表示および変更する機能。 

これは強力なアクセス許可であるため、信頼性の高いコードだけに付与するようにしてください。

ControlPrincipalプリンシパル オブジェクトを操作する機能。 
ControlThreadスレッドで特定の高度な操作を使用する機能。 
Executionコードを実行するためのアクセス許可。このアクセス許可がない場合、マネージ コードは実行されません。 

このフラグは、Deny、Assert、PermitOnly などのスタック修飾子で動的に使用する場合は無効です。

Infrastructureリモート処理コンテキスト シンク、エンボイ シンク、動的シンクの追加など、共通言語ランタイム インフラストラクチャへコードを組み込むためのアクセス許可。 
NoFlagsセキュリティ アクセスがありません。 
RemotingConfigurationリモート処理の型とチャネルを設定するためのアクセス許可。 
SerializationFormatterシリアル化サービスを提供する機能。シリアル化フォーマッタで使用します。 
SkipVerificationこのアセンブリでコードの検査をスキップする機能。このアクセス許可が付与されている場合は、検査できないコードを実行できます。 

これは強力なアクセス許可であるため、信頼性の高いコードだけに付与するようにしてください。

このフラグは、Deny、Assert、PermitOnly などのスタック修飾子で動的に使用する場合は無効です。

UnmanagedCodeアンマネージ コードを呼び出す機能。 

アンマネージ コードは、他のアクセス許可をバイパスすることを許す可能性があるため、これは信頼性の高いコードだけに与えるようにする必要がある危険なアクセス許可です。これは PInvoke または COM 相互運用機能を使用してネイティブ コードを呼び出すようなアプリケーションで使用します。

解説解説

この列挙体には、メンバ値のビットごとの組み合わせを可能にする FlagsAttribute 属性があります。

この列挙体は、SecurityPermission で使用されます。

注意に関するメモ注意

これらのフラグの多くは強力なため、信頼性の高いコードだけに付与するようにしてください。
