İş parçacığının geçerli sorumlusunu alır veya ayarlar (rol tabanlı güvenlik için).

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; }

static member CurrentPrincipal : System.Security.Principal.IPrincipal with get, set

Public Shared Property CurrentPrincipal As IPrincipal

Özellik Değeri

IPrincipal

IPrincipal Güvenlik bağlamını temsil eden bir değer.

Özel durumlar

SecurityException

Çağıranın sorumluyu ayarlamak için gereken izni yok.
