程序运行时间

1.Stopwatch sw = new Stopwatch();

 Stopwatch sw = new Stopwatch();
 sw.Start();
 .....................
 sw.Stop();
 Console.WriteLine(string.Format("Elapsed Time is {0} Milliseconds", sw.ElapsedMilliseconds));

2.DateTime beforDT = System.DateTime.Now;

DateTime beforDT = System.DateTime.Now;
..........................
DateTime afterDT = System.DateTime.Now;
TimeSpan ts = afterDT.Subtract(beforDT);
Console.WriteLine(ts.TotalMilliseconds.ToString());
