是的，你可以檢查PerformanceCounterCategory類的GetCounter()方法。你會拿一個PerformanceCounter[]和一些關於每個櫃檯的信息。

PerformanceCounterCategory pcc = new PerformanceCounterCategory(); 

// Retrieves the list of performance object instances that are associated with this category. 
foreach (string instanceName in pcc.GetInstanceNames()) 
    // Retrieves a list of the counters in a performance counter category that contains exactly one instance. 
    foreach (PerformanceCounter counter in pcc.GetCounters()) 
    { 
     // now you have the counter object that represents a PerformanceCounter to get some information about the performance counter 

     Console.WriteLine("Category: " + counter.Category); 
     Console.WriteLine("Instance Name: " + counter.InstanceName);  
     Console.WriteLine("Machine Name: " + counter.MachineName); 

     Console.WriteLine("Counter Name: " + counter.CounterName); 

     Console.WriteLine("Next Value: " + counter.NextValue()); 
    }
