I/O for processes

hi,
how i can retrieve the number of input/output operations generated by each process in the task manager using c#?

it is not possible in C#; you need low level programming.
you need to be familiar with interrupts.

I think it is not so hardcore, Win API and P/Invoke should be enought.

if it is possible with P/Invoke then you may find it in thid wiki:

http://www.pinvoke.net

i did a search in pinvoke.net with keyword: "process" but i did not find any to do the job.
