使用Stopwatch类来衡量.NET中方法执行的时间-
Stopwatch s = Stopwatch.StartNew();
现在设置一个函数并使用ElapsedMilliseconds属性获取执行时间(以毫秒为单位)-
s.ElapsedMilliseconds
让我们看完整的代码-
using System; using System.IO; using System.Diagnostics; public class Demo { public static void Main(string[] args) { Stopwatch s = Stopwatch.StartNew(); display(); for (int index = 0; index < 5; index++) { Console.WriteLine("Time taken: " + s.ElapsedMilliseconds + "ms"); } s.Stop(); } public static void display() { Console.WriteLine("演示功能!"); } }
输出结果
演示功能! Time taken: 15ms Time taken: 16ms Time taken: 16ms Time taken: 16ms Time taken: 16ms
