测量运行时间

System.Diagnostics.Stopwatch sw = new System.Diagnostics.Stopwatch();
sw.Start();
//这里填写要执行的代码

sw.Stop();
Console.WriteLine("总运行时间：" + sw.Elapsed);
Console.WriteLine("测量实例得出的总运行时间（毫秒为单位）：" + sw.ElapsedMilliseconds);

double duration = (double)sw.ElapsedTicks / (double)System.Diagnostics.Stopwatch.Frequency * 1000;
Console.WriteLine("测量实例得出的总运行时间（毫秒为单位）：" + duration.ToString("N4"));

Console.WriteLine("总运行时间(计时器刻度标识)：" + sw.ElapsedTicks);
Console.WriteLine("计时器是否运行：" + sw.IsRunning.ToString());
