用法

主要通过Stopwatch类来实现...

在开发、调试、测试、分析中非常实用.

Stopwatch sw = new Stopwatch();sw.Start();// 某些耗时的计算或任务...sw.Stop();var runtime = sw.ElapsedMilliseconds;

实例

新建一个叫做StopwatchDemo控制台应用程序

using System;using System.Diagnostics;namespace StopwatchDemo{    class Program    {        static void Main(string[] args)        {            Console.WriteLine("开始计算...");            Stopwatch sw = new Stopwatch();            sw.Start();            int sum = 0;            for (int i = 0, n = 100 * 10000; i < n; i++)            {                sum += i;            }            sw.Stop();            Console.WriteLine("执行百万次累加计算共耗时{0}毫秒", sw.ElapsedMilliseconds);            Console.WriteLine("累加结果为:{0}", sum);            Console.ReadKey();        }    }}
