Beispiele

Im folgenden Codebeispiel werden die Gatewayadressen für die Netzwerkschnittstellen auf dem lokalen Computer angezeigt.

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 );
         System::Collections::IEnumerator^ myEnum22 = addresses->GetEnumerator();

            GatewayIPAddressInformation^ address = safe_cast<GatewayIPAddressInformation^>(myEnum22->Current);
            Console::WriteLine( "  Gateway Address ......................... : {0}", 
               address->Address->ToString() );
         }
         Console::WriteLine();
      }

            }
            Console.WriteLine();
        }
    }
}

            Next address
            Console.WriteLine()
        End If
    Next adapter

End Sub

Hinweise

Gateways, die das Internetprotokoll Version 4 (IPv4) zum Weiterleiten von Paketen zwischen Netzwerken implementieren, werden von dieser Eigenschaft zurückgegeben.
