用C#语言获取CPU利用率

  CPU是计算机使用快慢的关键,因此要时时监控它,防止它使用率过高,造成卡机。以下是百分网小编整理的用C#语言获取CPU利用率,希望对大家有所帮助!更多信息请关注应届毕业生考试网!

  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 %
