Esempio

Nell'esempio di codice seguente vengono visualizzate le statistiche UDP per la versione specificata del protocollo Internet.

void ShowUdpStatistics( NetworkInterfaceComponent version )
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   UdpStatistics ^ udpStat = nullptr;
   switch ( version )
   {
      case NetworkInterfaceComponent::IPv4:
         udpStat = properties->GetUdpIPv4Statistics();
         Console::WriteLine( "UDP IPv4 Statistics" );
         break;

      case NetworkInterfaceComponent::IPv6:
         udpStat = properties->GetUdpIPv6Statistics();
         Console::WriteLine( "UDP IPv6 Statistics" );
         break;

      default:
         throw gcnew ArgumentException( "version" );
         break;
   }
   Console::WriteLine( "  Datagrams Received ...................... : {0}", udpStat->DatagramsReceived );
   Console::WriteLine( "  Datagrams Sent .......................... : {0}", udpStat->DatagramsSent );
   Console::WriteLine( "  Incoming Datagrams Discarded ............ : {0}", udpStat->IncomingDatagramsDiscarded );
   Console::WriteLine( "  Incoming Datagrams With Errors .......... : {0}", udpStat->IncomingDatagramsWithErrors );
   Console::WriteLine( "  UDP Listeners ........................... : {0}", udpStat->UdpListeners );
   Console::WriteLine( "" );
}

public static void ShowUdpStatistics(NetworkInterfaceComponent version)
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    UdpStatistics udpStat = null;

    switch (version)
    {
        case NetworkInterfaceComponent.IPv4:

            Console.WriteLine("UDP IPv4 Statistics");
            break;
        case NetworkInterfaceComponent.IPv6:
            udpStat = properties.GetUdpIPv6Statistics();
            Console.WriteLine("UDP IPv6 Statistics");
            break;
        default:
            throw new ArgumentException("version");
        //    break;
    }
    Console.WriteLine("  Datagrams Received ...................... : {0}",
        udpStat.DatagramsReceived);
    Console.WriteLine("  Datagrams Sent .......................... : {0}",
        udpStat.DatagramsSent);
    Console.WriteLine("  Incoming Datagrams Discarded ............ : {0}",
        udpStat.IncomingDatagramsDiscarded);
    Console.WriteLine("  Incoming Datagrams With Errors .......... : {0}",
        udpStat.IncomingDatagramsWithErrors);
    Console.WriteLine("  UDP Listeners ........................... : {0}",
        udpStat.UdpListeners);
    Console.WriteLine("");
}

Commenti

È possibile usare le UdpClient classi e Socket per creare applicazioni listener UDP.
