AppDomain.SetPrincipalPolicy(PrincipalPolicy) Methode

Definition

Gibt an, wie Haupt- und Identitätsobjekte an einen Thread angefügt werden sollen, wenn während der Ausführung in dieser Anwendungsdomäne versucht wird, den Thread an einen Prinzipal zu binden.Specifies how principal and identity objects should be attached to a thread if the thread attempts to bind to a principal while executing in this application domain.

public:
 virtual void SetPrincipalPolicy(System::Security::Principal::PrincipalPolicy policy);
public void SetPrincipalPolicy (System.Security.Principal.PrincipalPolicy policy);
abstract member SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit
override this.SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit
Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

Parameter

policy
PrincipalPolicy

Einer der PrincipalPolicy-Werte, die den Typ des Prinzipalobjekts angeben, das an Threads angefügt werden soll.One of the PrincipalPolicy values that specifies the type of the principal object to attach to threads.

Ausnahmen

Der Vorgang wird für eine entladene Anwendungsdomäne ausgeführt.The operation is attempted on an unloaded application domain.

Beispiele

Das folgende Beispiel zeigt die Auswirkung auf Threads, bei denen die SetPrincipalPolicy-Methode verwendet wird, um die Prinzipal Richtlinie der Anwendungsdomäne zu ändern.The following example shows the effect on threads of using the SetPrincipalPolicy method to change the principal policy of the application domain. Außerdem wird gezeigt, wie sich der Prinzipal, der für das Anfügen an Threads in der Anwendungsdomäne verfügbar ist, mithilfe der SetThreadPrincipal-Methode ändern kann.It also shows the effect of using the SetThreadPrincipal method to change the principal that is available for attaching to threads in the application domain.

Hinweise

Das Festlegen dieses Werts ist nur wirksam, wenn Sie ihn vor der Verwendung der Thread.CurrentPrincipal-Eigenschaft festlegen.Setting this value will only be effective if you set it before using the Thread.CurrentPrincipal property. Wenn Sie z. b. Thread.CurrentPrincipal auf einen bestimmten Prinzipal festgelegt haben (z. b. einen generischen Prinzipal) und dann die SetPrincipalPolicy-Methode verwenden, um die PrincipalPolicy auf WindowsPrincipalfestzulegen, bleibt der aktuelle Prinzipal der generische Prinzipal.For example, if you set Thread.CurrentPrincipal to a given principal (for example, a generic principal) and then use the SetPrincipalPolicy method to set the PrincipalPolicy to WindowsPrincipal, the current principal will remain the generic principal.
