c#如何获取cup，内存，硬盘的利用率？
如题，有做个这方面的吗？请给一下设计思路最好能提供代码，分不够在加．

如何用C＃实时获取CPU利用率！
using System;
using System.Diagnostics;
using System.Threading;
public class CpuLoadInfo
{
// auxiliary print methods
private static void Say ( string txt )
{
Console.WriteLine(txt);
}
// auxiliary print methods
private static void Say()
{
Say( " ");
}
// The main method. Command line arguments are ignored.
[STAThread]
public static void Main()
{
Say( "$Id: CpuLoadInfo.cs,v 1.2 2002/08/17 17:45:48 rz65 Exp $ ");
Say();
Say( "Attempt to create a PerformanceCounter instance: ");
Say( "Category name = " CategoryName);
Say( "Counter name = " CounterName);
Say( "Instance name = " InstanceName);
PerformanceCounter pc
= new PerformanceCounter(CategoryName,CounterName,InstanceName);
Say( "Performance counter was created. ");
Say( "Property CounterType: " pc.CounterType);
Say();
Say( "Property CounterHelp: " pc.CounterHelp);
Say();
Say( "Entering measurement loop. ");
while (true)
{
Thread.Sleep(1000); // wait for 1 second
float cpuLoad = pc.NextValue();
Say( "CPU load = " cpuLoad " %. ");
}
}
// constants used to select the performance counter.
private const string CategoryName = "Processor ";
private const string CounterName = "% Processor Time ";
private const string InstanceName = "_Total ";
}
这是在我计算机上的计算结果：
Entering measurement loop.
CPU load = 0 %.
CPU load = 1.941746 %.
CPU load = 4.854369 %.
CPU load = 10 %.
CPU load = 0 %.
CPU load = 2.999997 %.
CPU load = 0.9900987 %.
CPU load = 0 %.
