AppDomain.SetPrincipalPolicy(PrincipalPolicy) Yöntem

Tanım

Ad Alanı:

System

Bütünleştirilmiş Kod:

System.Runtime.dll

Kaynak:

AppDomain.cs

İş parçacığı bu uygulama etki alanında yürütülürken sorumluya bağlanmaya çalışırsa, sorumlu ve kimlik nesnelerinin bir iş parçacığına nasıl iliştirilmesi gerektiğini belirtir.

public:
 void SetPrincipalPolicy(System::Security::Principal::PrincipalPolicy policy);

public void SetPrincipalPolicy (System.Security.Principal.PrincipalPolicy policy);

member this.SetPrincipalPolicy : System.Security.Principal.PrincipalPolicy -> unit

Public Sub SetPrincipalPolicy (policy As PrincipalPolicy)

Parametreler

policy

PrincipalPolicy

İş parçacıklarına PrincipalPolicy eklenecek asıl nesnenin türünü belirten değerlerden biri.

Özel durumlar

AppDomainUnloadedException

İşlem, yüklenmemiş bir uygulama etki alanında deneniyor.

Örnekler

Aşağıdaki örnek, uygulama etki alanının asıl ilkesini değiştirmek için yöntemini kullanmanın SetPrincipalPolicy iş parçacıkları üzerindeki etkisini gösterir. Ayrıca, uygulama etki alanındaki iş parçacıklarına eklemek için kullanılabilen sorumluyu değiştirmek için yöntemini kullanmanın SetThreadPrincipal etkisini gösterir.

Açıklamalar

Bu değerin ayarlanması yalnızca özelliğini kullanmadan Thread.CurrentPrincipal önce ayarlarsanız etkili olur. Örneğin, belirli bir sorumluya (örneğin, genel bir sorumlu) ayarlayıp Thread.CurrentPrincipal yöntemini kullanarak SetPrincipalPolicy olarak ayarlarsanız PrincipalPolicyWindowsPrincipal, geçerli sorumlu genel sorumlu olarak kalır.
