Ejemplos

En el ejemplo siguiente se muestra información de tipo para todas las interfaces del equipo local.

void DisplayTypeAndAddress()
{
   IPGlobalProperties ^ computerProperties = IPGlobalProperties::GetIPGlobalProperties();
   array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
   Console::WriteLine( "Interface information for {0}.{1}     ", computerProperties->HostName, computerProperties->DomainName );
   System::Collections::IEnumerator^ myEnum27 = nics->GetEnumerator();
   while ( myEnum27->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum27->Current);
      IPInterfaceProperties ^ properties = adapter->GetIPProperties();
      Console::WriteLine( adapter->Description );
      Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );

Comentarios

Los tipos de interfaz se describen en detalle en la System.Net.NetworkInformation.NetworkInterfaceType documentación de enumeración.

En principio, esta propiedad puede devolver cualquier miembro de la NetworkInterfaceType enumeración. El valor específico que devuelve depende de las condiciones en tiempo de ejecución de la topología de red subyacente. Esto significa que:

• No es posible determinar de antemano qué valor devuelve la propiedad para una red determinada.

• Es posible que, en la práctica, en una red determinada, el intervalo completo de valores de enumeración no esté disponible. Por ejemplo, en una red Ethernet gigabit, es posible que la propiedad devuelva NetworkInterfaceType.Ethernet en lugar de NetworkInterfaceType.GigabitEthernet.
