C# StopWatch的使用

使用StopWatch类,可以计时,需引入System.Diagnostics 命名空间。

        static void Main(string[] args)
        {
            Console.WriteLine("Main Start....");
            Stopwatch sw = new Stopwatch();
            sw.Start();
            Thread.Sleep(3000);
            sw.Stop();
            Console.WriteLine("time elapsed "+sw.ElapsedMilliseconds);
            sw.Restart();                            //置0,并重新开始计时,     如果直接使用Start(),必须先调用Reset()置0
            Thread.Sleep(3000);
            sw.Stop();
            Console.WriteLine("Main end...." + sw.Elapsed);
            Console.ReadLine();
        }

运行结果:

Main Start....
time elapsed 3004
Main end....00:00:03.0093181
