写程序+控制cpu占用率-4+绘制CPU使用率的正弦曲线2+C#+实现

把上一节的通过C++ 控制CPU的占用率显示正弦曲线的代码用C# 重写了一次，效果要好一点。

C#代码：

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]);
            }
        }
    }
}

效果图：

1. 时间片为300

2. 时间片为250

3. 时间片为200
