You probably need to use another category 'Network Interface', see the answer here:
networking - How to display bytes received per second in C# - Stack Overflow[^]
But this is not process specific sadly ...

An alternative might be using the TCPView utility and using the output of that, see: TCPView for Windows - Windows Sysinternals | Microsoft Docs[^]

5. I have to add that the answer takes the first element of GetInstanceNames(), but when I tried it, I had to take the second element, or it wouldn't work.

Yes, it depends on the hardware (network cards, Wifi etc) that you have ...

Thanks , but i want get usage of application , in fact specific application .

RickZeeland 1-Aug-17 15:40pm

Use the command line version of TCPView, Tcpvcon and process the .CSV output of that in your program, good luck !

How can i use? I think for network interface stack overflow link which You introduced in this topic , I want specific application like a messenger , I need know which what can i use category name and instance name , thanks

RickZeeland 3-Aug-17 12:34pm

No, the stackoverflow solution is not suitable for a specific application.
Use the command line version of TCPView: Tcpvcon and process the .CSV output of that in your program. You can use Process.Start() to call Tcpvcon from C#.
