c# - Monitor a process's network usage?

Question

Is there a way in C# or C/C++ & Win32 to monitor a certain process's network usage (Without that application being built by you obviously)? I would like to monitor just 1 process for like an hour or so, then return the bytes used by only that process, such as limewire for example.

Is it possible? I know netstat -e on windows will tell you total bytes sent/received, but that is for all processes.

edit: If i can't return just one processes usage, how can i get the bytes sent/received by the entire system? as netstat displays except i just want the integers.

eg:

netstat -e

                           Received            Sent

Bytes                    2111568926      1133174989
Unicast packets             3016480         2711006
Non-unicast packets            3122            1100
Discards                          0               0
Errors                            0               0
Unknown protocols                 0

I just want to get 2 variables, like rec = 2111568926 and sent = 1133174989

Answer 1

You could use WinPcap for this or write your own device driver. I don't think there are any per process perfmon counters you can leverage.
