Hinweise

Diese Klasse stellt die Rollen des aktuellen Benutzers dar.

Konstruktoren

GenericPrincipal(IIdentity, String[])

Initialisiert eine neue Instanz der GenericPrincipal-Klasse aus einer Benutzeridentität und einem Array von Rollennamen, zu dem der von dieser Identität dargestellte Benutzer gehört.

Eigenschaften

Claims	Ruft eine Auflistung mit allen Ansprüchen aller Anspruchsidentitäten ab, die diesem Anspruchsprinzipal zugeordnet sind. (Geerbt von ClaimsPrincipal)
CustomSerializationData	Enthält alle zusätzlichen Daten, die von einem abgeleiteten Typ bereitgestellt werden. Wird in der Regel beim Aufrufen von WriteTo(BinaryWriter, Byte[]) festgelegt. (Geerbt von ClaimsPrincipal)
Identities	Ruft eine Auflistung mit allen Anspruchsidentitäten ab, die diesem Anspruchsprinzipal zugeordnet sind. (Geerbt von ClaimsPrincipal)
Identity	Ruft die GenericIdentity-Klasse des durch die aktuellen GenericPrincipal-Klasse dargestellten Benutzers ab.

Methoden

AddIdentities(IEnumerable<ClaimsIdentity>)	Fügt die angegebenen Anspruchsidentitäten diesem Anspruchsprinzipal hinzu. (Geerbt von ClaimsPrincipal)
AddIdentity(ClaimsIdentity)	Fügt die angegebene Anspruchsidentität diesem Anspruchsprinzipal hinzu. (Geerbt von ClaimsPrincipal)
Clone()	Gibt eine Kopie dieser Instanz zurück. (Geerbt von ClaimsPrincipal)
CreateClaimsIdentity(BinaryReader)	Erstellt eine neue Anspruchsidentität. (Geerbt von ClaimsPrincipal)
Equals(Object)	Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist. (Geerbt von Object)
FindAll(Predicate<Claim>)	Ruft alle Ansprüche ab, die dem angegebenen Prädikat entsprechen. (Geerbt von ClaimsPrincipal)
FindAll(String)	Ruft alle Ansprüche ab oder diejenigen, die den angegebenen Anspruchstyp aufweisen. (Geerbt von ClaimsPrincipal)
FindFirst(Predicate<Claim>)	Ruft den ersten Anspruch ab, der dem angegebenen Prädikat entspricht. (Geerbt von ClaimsPrincipal)
FindFirst(String)	Ruft den ersten Anspruch mit dem angegebenen Anspruchstyp ab. (Geerbt von ClaimsPrincipal)
GetHashCode()	Fungiert als Standardhashfunktion. (Geerbt von Object)
GetObjectData(SerializationInfo, StreamingContext)	Füllt das SerializationInfo-Objekt mit den für das Serialisieren des aktuellen ClaimsPrincipal-Objekts erforderlichen Daten. (Geerbt von ClaimsPrincipal)
GetType()	Ruft den Type der aktuellen Instanz ab. (Geerbt von Object)
HasClaim(Predicate<Claim>)	Ermittelt, ob eine der Anspruchsidentitäten, die diesem Anspruchsprinzipal zugeordnet sind, einen Anspruch enthält, der mit dem angegebenen Prädikat verglichen wird. (Geerbt von ClaimsPrincipal)
HasClaim(String, String)	Ermittelt, ob eine der Anspruchsidentitäten, die diesem Anspruchsprinzipal zugeordnet sind, einen Anspruch mit dem angegebenen Anspruchstyp und -wert enthält. (Geerbt von ClaimsPrincipal)
IsInRole(String)	Bestimmt, ob die aktuelle GenericPrincipal-Klasse zur angegebenen Rolle gehört.
MemberwiseClone()	Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object)
ToString()	Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object)
WriteTo(BinaryWriter)	Serialisiert mithilfe von BinaryWriter. (Geerbt von ClaimsPrincipal)
WriteTo(BinaryWriter, Byte[])	Serialisiert mithilfe von BinaryWriter. (Geerbt von ClaimsPrincipal)
