IPGlobalProperties.GetTcpIPv6Statistics Method

Note: This method is new in the .NET Framework version 2.0.

Provides Transmission Control Protocol/Internet Protocol version 6 (TCP/IPv6) statistical data for the local computer.

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

public abstract TcpStatistics GetTcpIPv6Statistics ()
public abstract TcpStatistics GetTcpIPv6Statistics ()
public abstract function GetTcpIPv6Statistics () : TcpStatistics

Return Value

A TcpStatistics object that provides TCP/IPv6 traffic statistics for the local computer.

Exception typeCondition

NetworkInformationException

The call to the Win32 function GetTcpStatistics failed.

PlatformNotSupportedException

The local computer is not running an operating system that supports IPv6.

TCP is a transport layer protocol responsible for reliably sending and receiving data packets. It is defined in IETF RFC 793.

For details on the TCP traffic statistics that are available to applications, see the TcpStatistics class documentation. Note that the object returned by this method reflects the statistics as of the time the TcpStatistics object is created. This information is not updated dynamically.

The following example displays the TCP/IP statistics for the local computer.

public static void ShowTcpStatistics(NetworkInterfaceComponent version)
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    TcpStatistics tcpstat = null;
    Console.WriteLine("");
    switch (version)
    {
        case NetworkInterfaceComponent.IPv4:
             tcpstat = properties.GetTcpIPv4Statistics();
            Console.WriteLine("TCP/IPv4 Statistics:");
            break;
        case NetworkInterfaceComponent.IPv6:
            tcpstat = properties.GetTcpIPv6Statistics();
            Console.WriteLine("TCP/IPv6 Statistics:");
            break;
        default:
            throw new ArgumentException("version");
            break;
    }
    Console.WriteLine("  Minimum Transmission Timeout............. : {0}", 
        tcpstat.MinimumTransmissionTimeout);
    Console.WriteLine("  Maximum Transmission Timeout............. : {0}", 
        tcpstat.MaximumTransmissionTimeout);
        
    Console.WriteLine("  Connection Data:");
    Console.WriteLine("      Current  ............................ : {0}", 
    tcpstat.CurrentConnections);
    Console.WriteLine("      Cumulative .......................... : {0}", 
        tcpstat.CumulativeConnections);
    Console.WriteLine("      Initiated ........................... : {0}", 
        tcpstat.ConnectionsInitiated);
    Console.WriteLine("      Accepted ............................ : {0}", 
        tcpstat.ConnectionsAccepted);
    Console.WriteLine("      Failed Attempts ..................... : {0}", 
        tcpstat.FailedConnectionAttempts);
    Console.WriteLine("      Reset ............................... : {0}", 
        tcpstat.ResetConnections);
        
    Console.WriteLine("");
    Console.WriteLine("  Segment Data:");
    Console.WriteLine("      Received  ........................... : {0}", 
        tcpstat.SegmentsReceived);
    Console.WriteLine("      Sent ................................ : {0}", 
        tcpstat.SegmentsSent);
    Console.WriteLine("      Retransmitted ....................... : {0}", 
        tcpstat.SegmentsResent);
    
    Console.WriteLine("");
