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();
        }
    }
}
