.Net中获取程序执行时间的方法

1. 利用System.Diagnostics.StopWatch:

代码 class Timing

{

TimeSpan duration;

public Timing()

{

duration =new TimeSpan(0);

}

public void stopTime()

{

duration =Process.GetCurrentProcess().TotalProcessorTime;

}

public void startTime()

{

GC.Collect();

GC.WaitForPendingFinalizers();

}

public TimeSpan Result()

{

return duration;

}

}

class chapter1

{

static void Main()

{

int[] nums = new int[100000];

BuildArray(nums);

Timing tobj = new Timing();

tobj.startTime();

DisplayNums(nums);

tobj.stopTime();

Console.WriteLine("Time: " + tobj.Result().TotalSeconds);

}

static void BuildArray(int[] arr)

{

for (int i = 0; i <= 99999; i++)

arr[i] = i;

}

static void DisplayNums(int[] arr)

{

for (int i = 0; i <= arr.GetUpperBound(0); i++)

Console.WriteLine(arr[i] + "");

}

}
