方法一:
//实例化一个计时器
Stopwatch watch = new Stopwatch();
//开始计时
watch.Start();
//此处为要计算的运行代码
for (int i = 1; i < 1000000; i++) { } // Execute the task to be timed
//结束计时
watch.Stop();
//获取当前实例测量得出的总运行时间(以毫秒为单位)
string time = watch.ElapsedMilliseconds.ToString();
//说明:Stopwatch提供了几个方法用以控制Stopwatch对象。Start方法开始一个计时操作,Stop方法停止计时。为避免这种情况,在第二次计时前用Reset方法将对象归零
Console.WriteLine("Elapsed: {0}",watch.Elapsed);
Console.WriteLine("In milliseconds: {0}",watch.ElapsedMilliseconds);
Console.WriteLine("In timer ticks: {0}",watch.ElapsedTicks);
方法二:
DateTime startTime = DateTime.Now;
Console.WriteLine ("Started: {0}", startTime);
// Execute the task to be timed
for (int i=1; i < 100000; i++){}
DateTime stopTime = DateTime.Now;
Console.WriteLine ("Stopped: {0}", stopTime);
TimeSpan elapsedTime = stopTime - startTime;
Console.WriteLine ("Elapsed: {0}", elapsedTime);
Console.WriteLine ("in hours :" + elapsedTime.TotalHours);
Console.WriteLine ("in minutes :" + elapsedTime.TotalMinutes);
Console.WriteLine ("in seconds :" + elapsedTime.TotalSeconds);
Console.WriteLine ("in milliseconds:" + elapsedTime.TotalMilliseconds);
