You'll need to use a Performance Counter. See this CP article:

An Introduction To Performance Counters[^]

Thanks , This is for retrieve network usage by process?

Ravi Bhavnani 7-Sep-17 17:55pm

Yes. See this SO post for an example:

Just copy and past but i get this error :
System.InvalidOperationException: 'Counter is single instance, instance name 'not found' is not valid for this counter category.'

So debug it and determine what's causing the problem. Blind copying and pasting is not the way to write code. If you have a specific question, we'll try to help you. But we're not here to do your work for you. CP is a volunteer site and we all have real jobs that occupy our time.

i think u didn't understand well i did copy and paste and didn't touch the code and with this i wanted to prove that i didn't do any changes to get errors and its been a long time that trying to solve this problem , now i get this error (System.InvalidOperationException: 'Counter is single instance, instance name 'not found' is not valid for this counter category.) do you have any solution for solving this problem if test this code see that you get this error or not.

> i didn't do any changes to get errors
That's good - I understand.

My point is, we can't debug this problem for you. You have debugger and the MSDN docs at your disposal, so please use both. It will be easier for us to help you if you narrow down the issue to a specific problem. But don't expect us to drop everything and test this code for you. Have you browsed Stack Overflow for similar questions? Simply saying "I did what you suggested and it didn't work" is not fair to those who volunteer their time to help you.

Yes , i asking in StackOverflow and MSDN and c-sharpcorner and etc , i can't debug this code , and i need help to debug , can you help me ? thanks for answer

You said you didn't modify the code at all, right? Well, of course it won't work - it's looking for an app called CUPC.exe. Did you even take the trouble to read and UNDERSTAND the code? I think not.

Armin.Engineer 8-Sep-17 3:56am

yes , I modify this code and replace another process instead of CPUC.exe , I did read code and nearly understand it , if i'm not mistaking i found this code once with google search and modified and didn't worked.

OK, I think I found the problem. Performance tracking of network utilization (a measure of upload and download rates) is specific to a network adapter, not an application (at least I don't know how to obtain the value for a specific app.

I was able to write a small console app that tracks network utilization for all network adapters installed on the system. The app is based on code I founs on SO. You can download the source code from:

So did you try the sample I uploaded for you?
