Thread.CurrentPrincipal Thread.CurrentPrincipal Thread.CurrentPrincipal Thread.CurrentPrincipal Property

Определение

Возвращает или задает текущего участника потока (для безопасности на основе ролей). 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
Значение свойства

Значение IPrincipal, представляющее контекст безопасности. An IPrincipal value representing the security context.

Исключения

Вызывающий объект не имеет разрешений, необходимых для задания участника. The caller does not have the permission required to set the principal.

Примеры

В следующем примере кода показано, как задание и получение участника потока.The following code example shows how to set and retrieve the principal of a thread.

using namespace System;

int main()
{
   array<String^>^rolesArray = {"managers","executives"};
   try
   {
      
      // 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 );
}

            // Set the principal to a new generic principal.
            Thread.CurrentPrincipal = 
                new GenericPrincipal(new GenericIdentity(
