類名：TimeStone

功能：輸出一段代碼的運行耗時

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
*/
}

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