Contoh

Contoh berikut menunjukkan penggunaan WindowsBuiltInRole enumerasi.

      AppDomain^ myDomain = Thread::GetDomain();

      myDomain->SetPrincipalPolicy( PrincipalPolicy::WindowsPrincipal );
      WindowsPrincipal^ myPrincipal = dynamic_cast<WindowsPrincipal^>(Thread::CurrentPrincipal);

      Console::WriteLine( "{0} belongs to: ", myPrincipal->Identity->Name );

      Array^ wbirFields = Enum::GetValues( WindowsBuiltInRole::typeid );

      for each ( Object^ roleName in wbirFields )
      {
         try
         {
            Console::WriteLine( "{0}? {1}.", roleName,

Keterangan

Peran ini mewakili grup Windows lokal yang umum untuk sebagian besar penginstalan Windows NT, Windows 2000 dan Windows XP.

Catatan

Di Windows Vista, Kontrol Akun Pengguna (UAC) menentukan hak istimewa pengguna. Jika Anda adalah anggota grup Administrator Bawaan, Anda diberi dua token akses run-time: token akses pengguna standar dan token akses administrator. Secara default, Anda berada dalam peran pengguna standar. Saat Anda mencoba melakukan tugas yang memerlukan hak istimewa administratif, Anda dapat meningkatkan peran Anda secara dinamis dengan menggunakan kotak dialog Persetujuan. Kode yang menjalankan IsInRole metode tidak menampilkan kotak dialog Persetujuan. Kode mengembalikan false jika Anda berada dalam peran pengguna standar, bahkan jika Anda berada di grup Administrator Bawaan. Anda dapat meningkatkan hak istimewa sebelum menjalankan kode dengan mengklik kanan ikon aplikasi dan menunjukkan bahwa Anda ingin menjalankan sebagai administrator.
