推荐答案

这是非常好的，但为了模拟一些时间的推移，我们需要运行需要一些时间，这就是在第二个例子中很清楚的命令。

That's very nice, however in order to simulate some time passing we need to run a command that takes some time and that's very clear in second example.

然而，使用一个for循环永远做一些功能性的风格需要大量的设备资源，相反，我们可以使用垃圾收集器做一些事情这样的。

However, the style of using a for loop to do some functionality forever takes a lot of device resources and instead we can use the Garbage Collector to do some thing like that.

我们可以看到在code这个修改从同一本书CLR通过C＃第三版。

We can see this modification in the code from the same book CLR Via C# Third Ed.

using System;
using System.Threading;

public static class Program {

   public static void Main() {
      // Create a Timer object that knows to call our TimerCallback
      // method once every 2000 milliseconds.
      Timer t = new Timer(TimerCallback, null, 0, 2000);
      // Wait for the user to hit <Enter>
      Console.ReadLine();
   }

   private static void TimerCallback(Object o) {
      // Display the date/time when this method got called.
      Console.WriteLine("In TimerCallback: " + DateTime.Now);
      // Force a garbage collection to occur for this demo.
      GC.Collect();
   }
}
