性能调优工具类TimeStone

类名：TimeStone

功能：输出一段代码的运行耗时

用法：

 

static void Main(string[] args)
        {
            new TimeStone("Main", "start");
            Thread.Sleep(1000);
            new TimeStone("Main", "Sleep1");
            Thread.Sleep(2000);
            new TimeStone("Main", "Sleep2");
            Thread.Sleep(3000);
            new TimeStone("Main", "Sleep3");

            Console.Read();

            /*
            Output:
            
            TimeStone: Main$Sleep1 Took 1031 Ms
            TimeStone: Main$Sleep2 Took 2000 Ms
            TimeStone: Main$Sleep3 Took 3000 Ms             
             */
        }

输出：　 TimeStone: Main$Sleep1 Took 1031 Ms
            TimeStone: Main$Sleep2 Took 2000 Ms
            TimeStone: Main$Sleep3 Took 3000 Ms
