Needs to get an exact CPU usage of certain process.

Hi, thank you for your attention, first.

Now, I need to get an exact CPU usage of certain process.

I googled all day long looking for this stuff

and I got this codes.

while (true)
{
using (PerformanceCounter pcProcess = new PerformanceCounter("Process", "% Processor Time", _testProcess.ProcessName))
{
pcProcess.NextValue();
System.Threading.Thread.Sleep(1000);
Console.WriteLine("Process:{0} CPU% {1}", _testProcess.ProcessName, pcProcess.NextValue());
}
}

It gives some value but unfortunately it is little bigger than it is supposed to be when it is compared to the one in the Task Manager.

When I try to get the entire CPU usage with the same way, it seems to be right

but I can't figure out why it is so much bigger than it should be.

Sometimes it is bigger than the entire CPU usage.

I need some help over here.

If I can, I want to give someone who solves this problem something.

Thanks and regards.

Andrew.
