寫程序+控制cpu占用率-4+繪制CPU使用率的正弦曲線2+C#+實現

把上一節的通過C++ 控制CPU的占用率顯示正弦曲線的代碼用C# 重寫了一次，效果要好一點。

上一節的連接： http://www.BkJia.com/kf/201110/107759.html

C#代碼：

 
using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Diagnostics; 
 
namespace cpu_4_2_csharp 
{ 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            const int SAMPLING_COUNT = 200; 
            const double PI = 3.14159; 
            const int TOTAL_AMPLITUDE = 250; // the length of each time piece 
 
            double[] busySpan=new double[SAMPLING_COUNT]; 
            int amplitude = TOTAL_AMPLITUDE / 2; 
            double radian = 0.0; 
            double radianIncreament = 2.0 / (double)SAMPLING_COUNT; 
 
            for (int i = 0; i < SAMPLING_COUNT; i++) 
            { 
                busySpan[i] = (double)(amplitude + Math.Sin(PI * radian) * amplitude); 
                radian += radianIncreament; 
            } 
 
            int startTick = Environment.TickCount; 
 
            for (int j = 0; ; j = (j + 1) % SAMPLING_COUNT) 
            { 
                startTick = Environment.TickCount; 
                while ((Environment.TickCount - startTick) < busySpan[j]) 
                { 
                    // 
                } 
                System.Threading.Thread.Sleep(TOTAL_AMPLITUDE-(int)busySpan[j]); 
            } 
        } 
    } 
} 

效果圖：

1. 時間片為300

2. 時間片為250

3. 時間片為200
