每个应用程序中的互联网使用情况

发布于 2024-10-17 11:09:23 字数 72 浏览 1 评论 0原文

我想问我如何获得某些应用程序（如流媒体等）使用的互联网流量。我想用 C# 制作一个程序，但我不知道如何启动它....给一些建议谢谢

作为起点，我会查看 WinSock API。您可能会找到一种在每个进程的基础上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。我从网络搜索< /a>:

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);
      }
}

As a starting point I'd look at the WinSock API. You may find a way of pulling traffic information on a per process basis.
If you want to see total network usage, I'd use the Performance Monitoring tools. I found this example from a web search:

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);
      }
}

据我所知，不存在测量每个应用程序的网络带宽的标准方法。使用标准方法可以获得的最多结果基本上就是 netstat 和 perfmon 显示的内容。计算每个应用程序指标的唯一方法是编写 NDIS 筛选器驱动程序，或使用现有的筛选器驱动程序（例如 WinPcap）。但这两种方法都必须在每台目标计算机上安装驱动程序。
