[c#] What is the correct Performance Counter to get CPU and Memory Usage of a Process?

How can I get the CPU and Memory usage of a particular process using the .NET PerformanceCounter class? And also what is the difference between

Processor\% Processor Time and Process\% Processor Time?

I am a bit confused between these two.

Pelo Hyper-V:

private PerformanceCounter theMemCounter = new PerformanceCounter(
    "Hyper-v Dynamic Memory VM",
    "Physical Memory",
    Process.GetCurrentProcess().ProcessName);
