Property Value

Type: System::Int64

An Int64 value that specifies the total number of received UDP datagrams that were discarded because there was no listening application at the destination port.

To find the total number of datagrams that could not be delivered, add the values that were returned by this property and the IncomingDatagramsWithErrors property.

The following code example displays the UDP statistics for the specified Internet Protocol version.

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( "" );
}
