示例

以下示例显示本地计算机的 TCP/IP 统计信息。

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("");

注解

TCP 是一种传输层协议，负责可靠地发送和接收数据包。 它在 IETF RFC 793 中定义。
