Hinweise

Achtung

Die Codezugriffssicherheit (CAS, Code Access Security) ist in allen Versionen von .NET Framework und .NET veraltet. Aktuelle Versionen von .NET berücksichtigen keine CAS-Anmerkungen und erzeugen Fehler, wenn CAS-bezogene APIs verwendet werden. Entwickler*innen sollten alternative Mittel zum Ausführen von Sicherheitsaufgaben suchen.

Codezugriffsberechtigungen verwenden einen Stapellauf, um sicherzustellen, dass allen Aufrufenden des Codes eine Berechtigung erteilt wurde. Wenn ein Berechtigungsobjekt ist null, wird es genauso behandelt wie ein Berechtigungsobjekt mit dem Status PermissionState.None.

Der Aufrufstapel wird in der Regel als nach unten wächst dargestellt, sodass Methoden höher im Aufrufstapel aufgerufen werden, die im Aufrufstapel niedriger sind.

Erben der CodeAccessPermission -Klasse muss die vollständige Vertrauenswürdigkeit gewährt werden, damit sie ordnungsgemäß als Berechtigungen funktionieren, die die Sicherheitsinfrastruktur erweitern. Um festzustellen, dass die Erben vollständig vertrauenswürdig sind, CodeAccessPermission gibt ein für ControlEvidencetrue = und aus.InheritanceDemandControlPolicy = true

Hinweise für Ausführende

Wenn Sie von erben CodeAccessPermission, müssen Sie auch die IUnrestrictedPermission -Schnittstelle implementieren.

Die folgenden CodeAccessPermission Member müssen überschrieben werden: Copy(), Intersect(IPermission), IsSubsetOf(IPermission), ToXml()FromXml(SecurityElement), und Union(IPermission).

Sie müssen auch einen Konstruktor definieren, der einen PermissionState als einzigen Parameter annimmt.

Sie müssen das SerializableAttribute Attribut auf eine Klasse anwenden, die von CodeAccessPermissionerbt.

Konstruktoren

CodeAccessPermission()
Veraltet.

Initialisiert eine neue Instanz der CodeAccessPermission-Klasse.

Methoden

Assert()
Veraltet.

Deklariert, dass der aufrufende Code auf die durch eine Berechtigungsforderung geschützte Ressource über den diese Methode aufrufenden Code zugreifen kann, auch wenn Aufrufern einer höheren Ebene im Stapel keine Berechtigung zum Zugreifen auf die Ressource erteilt wurde. Die Verwendung von Assert() kann zu Sicherheitsproblemen führen.

Copy()
Veraltet.

Ist diese Methode durch eine abgeleitete Klasse implementiert, erstellt sie eine identische Kopie des aktuellen Berechtigungsobjekts und gibt diese Kopie zurück.

Demand()
Veraltet.

Erzwingt zur Laufzeit eine SecurityException, wenn nicht allen Aufrufern, die in der Aufrufliste höher eingestuft sind, die Berechtigung gewährt wurde, die von der aktuellen Instanz angegeben wird.

Deny()
Veraltet.
Veraltet.

Verhindert, dass in der Aufrufliste höher eingestufte Aufrufer den Code verwenden, der diese Methode aufruft, um auf die Ressource zuzugreifen, die von der aktuellen Instanz angegeben wird.

Equals(Object)
Veraltet.

Bestimmt, ob das angegebene CodeAccessPermission-Objekt und das aktuelle CodeAccessPermission-Objekt gleich sind.

Equals(Object)
Veraltet.

Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist.

(Geerbt von Object)
FromXml(SecurityElement)
Veraltet.

Rekonstruiert beim außer Kraft setzen in einer abgeleiteten Klasse ein Sicherheitsobjekt mit einem angegebenen Zustand aus einer XML-Codierung.

GetHashCode()
Veraltet.

Ruft einen Hashcode für das CodeAccessPermission-Objekt ab, das sich für die Verwendung in Hashalgorithmen und Datenstrukturen eignet, z.B. in einer Hashtabelle.

GetHashCode()
Veraltet.

Fungiert als Standardhashfunktion.

(Geerbt von Object)
GetType()
Veraltet.

Ruft den Type der aktuellen Instanz ab.

(Geerbt von Object)
Intersect(IPermission)
Veraltet.

Bewirkt, dass bei der Implementierung durch eine abgeleitete Klasse eine Berechtigung, die die Schnittmenge der aktuellen Berechtigung und der angegebenen Berechtigung darstellt, erstellt und zurückgegeben wird.

IsSubsetOf(IPermission)
Veraltet.

Bestimmt bei der Implementierung durch eine abgeleitete Klasse, ob die aktuelle Berechtigung eine Teilmenge der angegebenen Berechtigung ist.

MemberwiseClone()
Veraltet.

Erstellt eine flache Kopie des aktuellen Object.

(Geerbt von Object)
PermitOnly()
Veraltet.

Verhindert, dass in der Aufrufliste höher eingestufte Aufrufer den Code, der diese Methode aufruft, verwenden, um auf alle Ressourcen außer die Ressource zuzugreifen, die von der aktuellen Instanz angegeben wird.

RevertAll()
Veraltet.

Veranlasst, dass alle vorherigen Überschreibungen für den aktuellen Frame entfernt werden und nicht mehr wirksam sind.

RevertAssert()
Veraltet.

Veranlasst, dass alle vorherigen Assert() für den aktuellen Frame entfernt werden und nicht mehr wirksam sind.

RevertDeny()
Veraltet.
Veraltet.

Veranlasst, dass alle vorherigen Deny() für den aktuellen Frame entfernt werden und nicht mehr wirksam sind.

RevertPermitOnly()
Veraltet.

Veranlasst, dass alle vorherigen PermitOnly() für den aktuellen Frame entfernt werden und nicht mehr wirksam sind.

ToString()
Veraltet.

Erstellt eine Zeichenfolgendarstellung des aktuellen Berechtigungsobjekts und gibt diese zurück.

ToXml()
Veraltet.

Erstellt bei Überschreibung in einer abgeleiteten Klasse eine XML-Codierung des Sicherheitsobjekts und seines aktuellen Zustands.

Union(IPermission)
Veraltet.

Erstellt beim Überschreiben in einer abgeleiteten Klasse eine Berechtigung als Kombination der aktuellen und der angegebenen Berechtigung.
