C#中提供的精准测试程序运行时间的类Stopwatch

在需要对程序的执行时间进行精准测试的程序员,不妨使用.Net提供的Stopwatch类,它的命名空间是:System.Diagnostics
代码如下:

    using System; 
    using System.Collections.Generic; 
    using System.Text; 
    using System.Diagnostics; 
      
     
    namespace StopWatch 
    { 
        class Program 
        { 
            static void Main(string[] args) 
            { 
                Stopwatch sw = new Stopwatch(); 
                sw.Start(); 
                //这里填写要执行的代码 
               sw.Stop(); 
               Console.WriteLine("总运行时间:" + sw.Elapsed); 
               Console.WriteLine("测量实例得出的总运行时间(毫秒为单位):" + sw.ElapsedMilliseconds); 
                Console.WriteLine("总运行时间(计时器刻度标识):" + sw.ElapsedTicks); 
                Console.WriteLine("计时器是否运行:" + sw.IsRunning.ToString()); 
           } 
        } 
    }

运行结果如下:
总运行时间:00:00:00.0000013
测量实例得出的程序运行时间(毫秒为单位):0
总运行时间(计时器刻度标识):5
计时器是否运行:False

using System;
    using System.Diagnostics;

    namespace StopWatchClass
    {
        class Program
        {
            static void Main(string[] args)
            {
                Stopwatch timer = new Stopwatch();
                long total = 0;

                timer.Start();
                for (int i = 1; i <= 10000000; i++)
                {
                    total += i;
                }

                timer.Stop();

                decimal micro = timer.Elapsed.Ticks / 10m;
                Console.WriteLine("Execution time was {0:F1} microseconds.", micro);
            }
        }
    }
