Exemples

L’exemple de code suivant affiche les adresses de passerelle pour les interfaces réseau sur l’ordinateur local.

void DisplayGatewayAddresses()
{
   Console::WriteLine( "Gateways" );
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum21 = adapters->GetEnumerator();
   while ( myEnum21->MoveNext() )

      GatewayIPAddressInformationCollection ^ addresses = adapterProperties->GatewayAddresses;
      if ( addresses->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
