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
本代码示例展示了如何使用C#创建一个性能计数器实例来测量CPU负载。通过设置性能计数器的类别名称为Processor、计数器名称为% Processor Time以及实例名称为_Total,可以获取整个系统的CPU利用率,并实时显示每秒的CPU负载百分比。
