Write programs + control cpu usage-4 + draw a sine curve of CPU usage 2 + C # + Implementation

The code used to control the CPU usage through C ++ in the previous section to display the sine curve is rewritten with C #, which is better.

Connection in the previous section: http://www.bkjia.com/kf/201110/107759.html

 

C # code:

 
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_amplece = 250; // the length of each time piece
 
Double [] busySpan = new double [SAMPLING_COUNT];
Int ampl_= 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) * amplian );
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_ampl--(int) busySpan [j]);
}
}
}
}

:

1. The time slice is 300

 

 

2. The time slice is 250

 

 

3. The time slice is 200
