作为起点，我会查看 WinSock应用程序接口(interface)。您可能会找到一种基于每个进程提取流量信息的方法。如果您想查看总网络使用情况，我会使用性能监控工具。我从 web search 中找到了这个例子:

private static void ShowNetworkTraffic()
{
     PerformanceCounterCategory performanceCounterCategory = new PerformanceCounterCategory("Network Interface");
     string instance = performanceCounterCategory.GetInstanceNames()[0]; // 1st NIC !
     PerformanceCounter performanceCounterSent = new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance);
     PerformanceCounter performanceCounterReceived = new PerformanceCounter("Network Interface", "Bytes Received/sec", instance);

     for (int i = 0; i < 10; i++)
     {
         Console.WriteLine("bytes sent: {0}k\tbytes received: {1}k", performanceCounterSent.NextValue() / 1024, performanceCounterReceived.NextValue() / 1024);
         Thread.Sleep(500);
      }
}
