C#中方法的持续时间,时间开始和结束时间

它具有普通秒表的功能,包括开始,停止,重置,经过的时间等等.

这非常适合测量特定的代码块或方法.但是,除了执行的持续时间之外,您还要说明您需要开始和结束时间.您可以通过继承Stopwatch类并使用几个DateTime属性扩展它来创建自定义秒表.

public class CustomStopwatch : Stopwatch
    {

        public DateTime? StartAt { get; private set; }
        public DateTime? EndAt { get; private set; }


        public void Start()
        {
            StartAt = DateTime.Now;

            base.Start();
        }

        public void Stop()
        {
            EndAt = DateTime.Now;

            base.Stop();
        }

        public void Reset()
        {
            StartAt = null;
            EndAt = null;

            base.Reset();
        }

        public void Restart()
        {
            StartAt = DateTime.Now;
            EndAt = null;

            base.Restart();
        }

    }

并像这样使用它：

CustomStopwatch sw = new CustomStopwatch();
sw.Start();
Thread.Sleep(2342); // just to use some time,logic would be in here somewhere.
sw.Stop();
Console.WriteLine("Stopwatch elapsed: {0},StartAt: {1},EndAt: {2}",sw.ElapsedMilliseconds,sw.StartAt.Value,sw.EndAt.Value);
