Contoh

Kode berikut menunjukkan penggunaan GenericPrincipal konstruktor. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan untuk GenericPrincipal kelas .

WindowsIdentity^ windowsIdentity = WindowsIdentity::GetCurrent();
array<String^>^roles = gcnew array<String^>(10);
if ( windowsIdentity->IsAuthenticated )
{
   
   // Add custom NetworkUser role.
   roles[ 0 ] = L"NetworkUser";
}

if ( windowsIdentity->IsGuest )
{
   
   // Add custom GuestUser role.
   roles[ 1 ] = L"GuestUser";
}

if ( windowsIdentity->IsSystem )
{
   
   // Add custom SystemUser role.
   roles[ 2 ] = L"SystemUser";
}

// Construct a GenericIdentity object based on the current Windows
// identity name and authentication type.
String^ authenticationType = windowsIdentity->AuthenticationType;
String^ userName = windowsIdentity->Name;
GenericIdentity^ genericIdentity = gcnew GenericIdentity(
   userName,authenticationType );

// Construct a GenericPrincipal object based on the generic identity
// and custom roles for the user.
GenericPrincipal^ genericPrincipal = gcnew GenericPrincipal(
   genericIdentity,roles );

WindowsIdentity windowsIdentity = WindowsIdentity.GetCurrent();
string[] roles = new string[10];
