SecurityPermissionFlag-Enumeration
Gibt Zugriffsflags für das Sicherheitsberechtigungsobjekt an.
Diese Enumeration verfügt über ein FlagsAttribute -Attribut, das die bitweise Kombination der Memberwerte zulässt.
Namespace: System.Security.Permissions
Assembly: mscorlib (in mscorlib.dll)

Member
| Membername | Beschreibung | |
|---|---|---|
| AllFlags | Der uneingeschränkte Zustand der Berechtigung. | |
| Assertion | Die Fähigkeit zu bestätigen, dass alle Aufrufer dieses Codes über die erforderliche Berechtigung für den Vorgang verfügen. | |
| BindingRedirects | Die Berechtigung für die explizite Bindungsumleitung in der Anwendungskonfigurationsdatei. Dies umfasst die Umleitung von vereinheitlichten .NET Framework-Assemblys und von Assemblys außerhalb von .NET Framework. | |
| ControlAppDomain | Die Fähigkeit zum Erstellen und Bearbeiten von AppDomain. | |
| ControlDomainPolicy | Die Fähigkeit zum Angeben von Domänenrichtlinien. | |
| ControlEvidence | Die Fähigkeit zum Bereitstellen von Beweisen, einschließlich der Fähigkeit, die von der Common Language Runtime bereitgestellten Beweise zu ändern.
Diese Berechtigung ist äußerst weit reichend und sollte nur für sehr vertrauenswürdigen Code erteilt werden. |
|
| ControlPolicy | Die Fähigkeit zum Anzeigen und Ändern von Richtlinien.
Diese Berechtigung ist äußerst weit reichend und sollte nur für sehr vertrauenswürdigen Code erteilt werden. |
|
| ControlPrincipal | Die Fähigkeit zum Verändern des Hauptobjekts. | |
| ControlThread | Die Fähigkeit zum Verwenden bestimmter erweiterter Vorgänge in Threads. | |
| Execution | Berechtigung für den auszuführenden Code. Ohne diese Berechtigung wird verwalteter Code nicht ausgeführt.
Dieses Flag hat keine Auswirkungen, wenn es dynamisch mit Stapelmodifizierern wie Deny, Assert und PermitOnly verwendet wird. |
|
| Infrastructure | Berechtigung zum Einbinden von Code in die Infrastruktur der Common Language Runtime, z. B. für das Hinzufügen von Remotekontextempfängern, Botenempfängern und dynamischen Empfängern. | |
| NoFlags | Kein Sicherheitszugriff. | |
| RemotingConfiguration | Berechtigung zum Konfigurieren von Remotetypen und Channels. | |
| SerializationFormatter | Die Fähigkeit zum Bereitstellen von Serialisierungsdiensten. Wird durch Serialisierungsformatierer verwendet. | |
| SkipVerification | Die Fähigkeit, die Überprüfung von Code in dieser Assembly zu überspringen. Nicht überprüfbarer Code kann bei Erteilung dieser Berechtigung ausgeführt werden.
Diese Berechtigung ist äußerst weitreichend und sollte nur für sehr vertrauenswürdigen Code erteilt werden. Dieses Flag hat keine Auswirkungen, wenn es dynamisch mit Stapelmodifizierern wie Deny, Assert und PermitOnly verwendet wird. |
|
| UnmanagedCode | Die Fähigkeit, nicht verwalteten Code aufzurufen.
Da nicht verwalteter Code möglicherweise das Umgehen anderer Berechtigungen ermöglicht, ist dies eine riskante Berechtigung, die nur für äußerst vertrauenswürdigen Code erteilt werden sollte. Sie wird für Anwendungen wie das Aufrufen von systemeigenem Code mit PInvoke oder COM-Interop verwendet. |
Hinweise
Diese Enumeration verfügt über ein FlagsAttribute-Attribut, das die bitweise Kombination der Memberwerte zulässt.
Diese Enumeration wird von SecurityPermission verwendet.
Warnung
Viele dieser Flags sind sehr weitreichend und sollten nur für sehr vertrauenswürdigen Code erteilt werden.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, wie die SecurityPermissionFlag-Enumeration zum Verweigern und Anfordern von Sicherheitsberechtigungen verwendet wird.
