{
   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:

注解

此类的实例由 GetTcpIPv4Statistics 和 GetTcpIPv6Statistics 方法返回，使应用程序能够访问 TCP 流量信息。

此类中的信息与 中所述 https://www.ietf.org/rfc/rfc2012.txt的管理信息对象相关联。
