Hinweise

Ein PolicyStatement besteht aus einem Satz gewährter Berechtigungen und möglichen speziellen Attributen für die Codegruppe.

Richtlinienanweisungen werden in der Regel als Rückgabewert eines Resolve Vorgangs für verwendet PolicyLevel.

Konstruktoren

PolicyStatement(PermissionSet)	Veraltet. Initialisiert eine neue Instanz der PolicyStatement-Klasse mit der angegebenen PermissionSet.
PolicyStatement(PermissionSet, PolicyStatementAttribute)	Veraltet. Initialisiert eine neue Instanz der PolicyStatement-Klasse mit dem angegebenen PermissionSet und den angegebenen Attributen.

Eigenschaften

Attributes	Ruft die Attribute der Richtlinienanweisung ab oder legt diese fest.
AttributeString	Ruft eine Zeichenfolgendarstellung der Attribute für die Richtlinienanweisung ab.
PermissionSet	Veraltet. Ruft das PermissionSet der Richtlinienanweisung ab oder legt dieses fest.

Methoden

Copy()	Erstellt eine äquivalente Kopie der aktuellen Richtlinienanweisung.
Equals(Object)	Bestimmt, ob das angegebene PolicyStatement-Objekt und das aktuelle PolicyStatement-Objekt gleich sind.
Equals(Object)	Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist. (Geerbt von Object)
FromXml(SecurityElement)	Rekonstruiert aus einer XML-Codierung ein Sicherheitsobjekt mit einem angegebenen Zustand.
FromXml(SecurityElement, PolicyLevel)	Rekonstruiert aus einer XML-Codierung ein Sicherheitsobjekt mit einem angegebenen Zustand.
GetHashCode()	Ruft einen Hashcode für das PolicyStatement-Objekt ab, das sich für die Verwendung in Hashalgorithmen und Datenstrukturen eignet, z.B. in einer Hashtabelle.
GetHashCode()	Fungiert als Standardhashfunktion. (Geerbt von Object)
GetType()	Ruft den Type der aktuellen Instanz ab. (Geerbt von Object)
MemberwiseClone()	Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object)
ToString()	Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object)
ToXml()	Erstellt eine XML-Codierung des Sicherheitsobjekts und seines aktuellen Zustands.
ToXml(PolicyLevel)	Erstellt eine XML-Codierung des Sicherheitsobjekts und seines aktuellen Zustands.
