Hi. I'm using C#. i want to get download and upload usage of processes in bytes per seconds , How i must do this? for example an app how much is downloading or uploading right now. Thanks.

There are network monitoring tools that can do this...

Thanks , What tools are you talking about?

What I'm saying is that you should use some external network monitoring tools to do this - doing this inside of an application is very inefficient and usually highly in accurate.

I can't point you at a specific reference, since this is not my area of expertise, but Google is your friend in finding good monitoring solutions.
