C#实现获取CPU使用率的方法

无需多说，直接上代码

　　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";
　　}

 

F5就可以看到运行结果了
