C#基础_利用Stopwatch计时器可暂停计时，继续计时

最近程序上用到了计时功能，对某个模块进行计时，暂停的时候模块也需要暂停，启动的时候计时继续

用到了Stopwatch

Stopwatch的命名空间是using System.Diagnostics;

using System;

using System.Collections.Generic;

using System.Diagnostics;

using System.Linq;

using System.Text;

using System.Threading;

using System.Threading.Tasks;

namespace ConsoleApp3

{

    class Program

    {

        static void Main(string[] args)

        {

            Stopwatch sw = new Stopwatch();

            ////重新设置为零

            //sw.Reset();

            ////重新设置并开始计时

            //sw.Restart();

            ////结束计时

            //sw.Stop();

            //获取运行时间间隔

            TimeSpan ts = sw.Elapsed;

            //获取运行时间[毫秒]

            long times = sw.ElapsedMilliseconds;

            //获取运行的总时间

            long times2 = sw.ElapsedTicks;

            //判断计时是否正在进行[true为计时]

            bool isrun = sw.IsRunning;

            //获取计时频率

            long frequency = Stopwatch.Frequency;

            //计时开始

            sw.Start();

            Thread.Sleep(1000);

            //计时结束

            sw.Stop();

            Console.WriteLine(sw.ElapsedMilliseconds);

            Console.ReadLine();

            //计时开始

            sw.Start();

            Thread.Sleep(2000);

            //计时结束

            sw.Stop();

            Console.WriteLine(sw.ElapsedMilliseconds);

            sw.Start();

            Thread.Sleep(3000);

            //计时结束

            sw.Stop();

            Console.WriteLine(sw.ElapsedMilliseconds);

            Console.ReadLine();

        }

    }

}
