UdpStatistics.UdpListeners Property

 

Gets the number of local endpoints that are listening for User Datagram Protocol (UDP) datagrams.

Namespace:   System.Net.NetworkInformation
Assembly:  System (in System.dll)

public abstract int UdpListeners { get; }

Property Value

Type: System.Int32

An Int64 value that specifies the total number of sockets that are listening for UDP datagrams.

You can use the UdpClient and Socket classes to create UDP listener applications.

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

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

    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 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("");
}
