Thread.CurrentPrincipal Eigenschaft

Definition

Ruft den aktuellen Prinzipal des Threads (für rollenbasierte Sicherheit) ab oder legt diesen fest.Gets or sets the thread's current principal (for role-based security).

public:
 static property System::Security::Principal::IPrincipal ^ CurrentPrincipal { System::Security::Principal::IPrincipal ^ get(); void set(System::Security::Principal::IPrincipal ^ value); };
public static System.Security.Principal.IPrincipal CurrentPrincipal { get; set; }
member this.CurrentPrincipal : System.Security.Principal.IPrincipal with get, set
Public Shared Property CurrentPrincipal As IPrincipal

Eigenschaftswert

Ein IPrincipal-Wert, der den Sicherheitskontext darstellt.An IPrincipal value representing the security context.

Ausnahmen

Der Aufrufer verfügt nicht über die erforderliche Berechtigung zum Festlegen des Prinzipals.The caller does not have the permission required to set the principal.

Beispiele

Im folgenden Codebeispiel wird gezeigt, wie der Prinzipal eines Threads festgelegt und abgerufen wird.The following code example shows how to set and retrieve the principal of a thread.

using namespace System;

   array<String^>^rolesArray = {"managers","executives"};

   {
      
      // Set the principal to a new generic principal.
      Thread::CurrentPrincipal = gcnew GenericPrincipal( gcnew GenericIdentity( "Bob","Passport" ),rolesArray );
   }
   catch ( SecurityException^ secureException ) 
   {
      Console::WriteLine( "{0}: Permission to set Principal "
      "is denied.", secureException->GetType()->Name );
   }

   IPrincipal^ threadPrincipal = Thread::CurrentPrincipal;
   Console::WriteLine( "Name: {0}\nIsAuthenticated: {1}"
   "\nAuthenticationType: {2}", threadPrincipal->Identity->Name, threadPrincipal->Identity->IsAuthenticated.ToString(), threadPrincipal->Identity->AuthenticationType );
}
