在C#中使用特定服务的CPU使用情况

我想知道C#中特定服务的CPU使用情况。

PerformanceCounter正常工作:

PerformanceCounter counter = new PerformanceCounter("Process", "% Processor Time", "myprocess", true); double result = counter.NextValue(); 

但不包括服务:

  PerformanceCounter counter = new PerformanceCounter("Service", "% Processor Time", "myservice", true); double result = counter.NextValue(); 

性能计数器的正确名称是

 PerformanceCounter counter = new PerformanceCounter("Process", "% Processor Time", "ACService", true);
