【中文标题】如何监控特定应用程序的网络带宽使用情况？

【英文标题】：How to monitor the network bandwidth usage of a specific application?

【问题描述】：

我正在尝试学习如何监控特定应用程序的网络带宽使用情况。我正在查看IPv4InterfaceStatistics，但这似乎是在监控 NIC 卡的性能。 我想监控一个特定的应用程序，看看每秒消耗了多少带宽。 有谁知道如何做到这一点的例子？

【问题讨论】：

Windows 资源监视器。

@DeepakMishra 我想他想以编程方式解决这个问题，因为它是 C# 和堆栈，而不是服务器故障，但我可能是错的。

是的，我想以编程方式解决这个问题

【参考方案2】：

这是使用 PerformanceCounter 的修改版本：

var processFileName = Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName);
var bytesReceivedPerformanceCounter = new PerformanceCounter();
bytesReceivedPerformanceCounter.CategoryName = ".NET CLR Networking 4.0.0.0";
bytesReceivedPerformanceCounter.CounterName = "Bytes Received";
bytesReceivedPerformanceCounter.InstanceName = VersioningHelper.MakeVersionSafeName(processFileName, ResourceScope.Machine, ResourceScope.AppDomain);
bytesReceivedPerformanceCounter.ReadOnly = true;

Console.WriteLine("Bytes received: 0", bytesReceivedPerformanceCounter.RawValue);

【参考方案3】：

如果您熟悉 OSI 模型 http://en.wikipedia.org/wiki/OSI_model，您会发现您尝试与第 3 层交互，而您应该与第 7 层交互。

我与您使用的任何类的连接都可以测量发送的字节数，特别是如果您正在传输单个字节，（这是因为我不知道您的代码看起来如何），您应该能够计算一个时间除以秒数的字节数，你就会得到你的结果。
