如何获取每秒接收和发送的网络字节数对于C ++ for Windows中的进程（输入：进程ID或句柄）？

Question

I need to get network information per process just like in resource monitor. I need to find the received bytes/s & sent bytes/s.

I tried to get it using Win32_PerfRawData_PerfProc_Process class. But it gives IO, file bytes in addition to network details.

I tried to get details using Win32_PerfRawData_Tcpip_NetworkInterface class. But it gives details per Network interface.

Then I tried to use GetTcpStatistics function. For that MIB_IPSTATS has been used. MIB_IPSTATS shows cumulative results for entire process.

1. Are there any other MIB Structures to show these details per process manner?
2. how to get Bytes/s thing per process just like in resource monitor which is shown in Win32_PerfRawData_Tcpip_NetworkInterface as cumulated data for entire processes
3. Can I calculate Bytes/s using Win32_PerfRawData_PerfProc_Process class based on other values?
4. Are there any methods like GetProcessMemoryInfo ( this method is to get process memory) to get received and sent bytes per sec?
5. Are there any other methods to calculate them?

You might try looking into Performance Counters.

Here is a code project example of getting network speed using performance counters. It is in c# but you should be able to translate to c++.
