PermissionSetAttribute Klasse

Definition

Achtung

Code Access Security is not supported or honored by the runtime.

Lässt zu, dass Sicherheitsaktionen für PermissionSet mithilfe der deklarativen Sicherheit auf Code angewendet werden. Diese Klasse kann nicht vererbt werden.

Hinweise

Achtung

Code Access Security (CAS) ist in allen Versionen von .NET Framework und .NET veraltet. Aktuelle Versionen von .NET berücksichtigen CAS-Anmerkungen nicht und verursachen Fehler, wenn CAS-bezogene APIs verwendet werden. Entwickler sollten nach alternativen Mitteln suchen, um Sicherheitsaufgaben zu erledigen.

Die PermissionSetAttribute Eigenschaften Name, Fileund XML schließen sich gegenseitig aus, was bedeutet, dass ein Berechtigungssatz nur eine der folgenden Quellen als Quelle haben kann: einen benannten Berechtigungssatz, eine Datei, die eine XML-Darstellung eines Berechtigungssatzes enthält, oder eine Zeichenfolge, die eine XML-Darstellung eines Berechtigungssatzes enthält.

Der zulässige Bereich der Deklaration hängt vom SecurityAction verwendeten ab. Ein SecurityAction für ein PermissionSet ausgeführtes ist das Äquivalent zum Ausführen dieser Aktion für jede der Berechtigungen innerhalb des Satzes.

Die von einem Sicherheitsattribute deklarierten Sicherheitsinformationen werden in den Metadaten des Attributziels gespeichert und vom System zur Laufzeit aufgerufen. Sicherheitsattribute werden nur für deklarative Sicherheit verwendet. Verwenden Sie für imperative Sicherheit die entsprechende Berechtigungsklasse.
