C#——计时器的操作
我们可以用Stopwatch类获得程序的运行时间,在优化代码时,可以用此方法来查看优化前后程序所耗费的时间
static void Main(string[] args) { Stopwatch sw = new Stopwatch(); long num = 0; sw.Reset(); sw = Stopwatch.StartNew(); for (int i = 1; i < 100000000; i++) num += 1; sw.Stop(); TimeSpan el = sw.Elapsed; Console.WriteLine("花费 {0} ", el); long ms = sw.ElapsedMilliseconds; Console.WriteLine("花费 {0} 毫秒", ms); long tk = sw.ElapsedTicks; Console.WriteLine("花费 {0} ticks", tk); Console.ReadKey(); }
