TcpStatistics

範例

下列程式代碼範例會顯示指定之位址系列的 TCP 統計數據。

void ShowTcpStatistics( NetworkInterfaceComponent version )
{
   IPGlobalProperties ^ properties = IPGlobalProperties::GetIPGlobalProperties();
   TcpStatistics ^ tcpstat = nullptr;
   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 gcnew ArgumentException( "version" );
         break;
   }

    Console.WriteLine("      Sent ................................ : {0}",
        tcpstat.SegmentsSent);
    Console.WriteLine("      Retransmitted ....................... : {0}",
        tcpstat.SegmentsResent);

    Console.WriteLine("");
}

備註

和 GetTcpIPv6Statistics 方法會傳GetTcpIPv4Statistics回這個類別的實例，讓應用程式能夠存取 TCP 流量資訊。

這個類別中的資訊會與 中所述 https://www.ietf.org/rfc/rfc2012.txt的管理信息物件相互關聯。
