提供本機電腦的傳輸控制通訊協定/網際網路通訊協定第 4 版 (TCP/IPv4) 統計資料。

C# 
[System.Runtime.Versioning.UnsupportedOSPlatform("android")]
public abstract System.Net.NetworkInformation.TcpStatistics GetTcpIPv4Statistics();
C# 
public abstract System.Net.NetworkInformation.TcpStatistics GetTcpIPv4Statistics();

傳回

TcpStatistics

TcpStatistics 物件，其提供本機電腦的 TCP/IPv4 流量統計資料。

屬性
UnsupportedOSPlatformAttribute

例外狀況

NetworkInformationException

呼叫 Win32 函式 GetTcpStatistics 失敗。

範例

下列範例會顯示本機計算機的 TCP/IP 統計數據。

C# 
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("");
}

備註

TCP 是傳輸層通訊協議，負責可靠地傳送和接收數據封包。 它定義於 IETF RFC 793 中。

如需應用程式可用 TCP 流量統計資料的詳細資訊，請參閱 TcpStatistics 類別檔。 請注意，這個方法所傳回的物件會反映建立物件時所傳回的 TcpStatistics 統計數據。 此資訊不會動態更新。
