System.Timers.Timer 奇怪问题

using System;
using System.Timers;

public class Timer1
{
    public static void Main()
    {
        // Normally, the timer is declared at the class level, so
        // that it doesn't go out of scope when the method ends.
        // In this example, the timer is needed only while Main
        // is executing. However, KeepAlive must be used at the
        // end of Main, to prevent the JIT compiler from allowing
        // aggressive garbage collection to occur before Main
        // ends.
        System.Timers.Timer aTimer = new System.Timers.Timer();

        // Hook up the Elapsed event for the timer.
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

        // Set the Interval to 2 seconds (2000 milliseconds).
        aTimer.Interval = 2000;
        aTimer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the program.");
        Console.ReadLine();

        // Keep the timer alive until the end of Main.
        GC.KeepAlive(aTimer);
    }

    // Specify what you want to happen when the Elapsed event is
    // raised.
    private static void OnTimedEvent(object source, ElapsedEventArgs e)
    {
        Console.WriteLine("Hello World!");
    }
}

测试了这msdn官方的demo 发现一段时间后会自动停止，不知道怎么回事，请各位大大指教！ --------------------编程问答-------------------- 不会自动停止啊   只是在你敲了回车之后Console.ReadLine();执行完了控制台就关闭了程序结束了 --------------------编程问答-------------------- Console.ReadLine();会挂起。不知道你说的是不是这个。 --------------------编程问答-------------------- 你没有做任何操作？诡异应该是要读一个字符的。。。。。。

补充：.NET技术 ,  C#
