线程难点

Question

做了一个定时抓天气的线程, 在全局类里启动. 
一开始都好,但是不久(几个小时后)天气预报就不见了,线程莫名消失了 
请教高手,为什么 
线程程序 
public WeatherThread() 
{ 
        ThreadStart thr_start_func = new ThreadStart(threadProc); 
        fThread = new Thread(thr_start_func); 
        fThread.Name = "getWeather"; 
/*      fThread.IsBackground = true; 
        fThread.Start(); //starting the thread 
        flag = true; 
  */ 
}     public void trigger() 
    { 
        if (fThread.IsAlive) 
        { 
            fThread.Abort(); 
        } 
        else 
        { 
            fThread.IsBackground = true; 
            fThread.Start(); 
        } 
    }     public static void threadProc() 
    { 
        while (true) 
        { 
            try 
            { 
              Thread.Sleep(timeinternal * 1000); 
            } 
            catch (Exception) 
            { 
            } 
        }     } 
} 启动部分:global.asax 
    void Application_Start(object sender, EventArgs e) 
    { 
        // Code that runs on application startup 
        WeatherThread Wt = new WeatherThread(); 
        Wt.trigger(); 
    } 
    

Answer 1

 void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup 
            WeatherThread Wt = new WeatherThread();
            Wt.WeatherThread();
        }        Thread fThread = null;
        public void WeatherThread()
        {
            if (fThread == null)
            {
                ThreadStart thr_start_func = new ThreadStart(threadProc);
                fThread = new Thread(thr_start_func);
                fThread.Name = "getWeather";
            }
        }        public static void threadProc()
        {
            while (true)
            {
                try
                {
                    //获取代码块
                }
                catch 
                {
                    
                }
                finally
                {
                    Thread.Sleep(timeinternal * 1000);
                }
            }
        }

你的关键代码就给了这些？什么都没有做？：
public static void threadProc() 
    { 
        while (true) 
        { 
            try 
            { 
              Thread.Sleep(timeinternal * 1000); 
            } 
            catch (Exception) 
            { 
            } 
        } 
    }
