用C#語言獲取CPU利用率

　　using System;

　　using SystemDiagnostics;

　　using SystemThreading;

　　public class CpuLoadInfo

　　{

　　// auxiliary print methods

　　private static void Say ( string txt )

　　{

　　ConsoleWriteLine(txt);

　　}

　　// auxiliary print methods

　　private static void Say()

　　{

　　Say();

　　}

　　// The main method Command line arguments are ignored

　　[STAThread]

　　public static void Main()

　　{

　　Say($Id: CpuLoadInfocsv // :: rz 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(CategoryNameCounterNameInstanceName);

　　Say(Performance counter was created);

　　Say(Property CounterType: + pcCounterType);

　　Say();

　　Say(Property CounterHelp: + pcCounterHelp);

　　Say();

　　Say(Entering measurement loop);

　　while (true)

　　{

　　ThreadSleep(); // wait for second

　　float cpuLoad = pcNextvalue();

　　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;

　　}

　　這是在我計算機上的計算結果

　　Entering measurement loop

　　CPU load = %
