动态设置定时执行功能 [英] Execute function on timing set dynamically

问题描述

我有两个功能，如下所示:

I have two functions as following :

public void SendMessage()
{
     //Some Code
}

AND

AND

public void CheckReceivedMessage()
{ 
     //Some Code
}

现在，我要 CheckReceivedMessage()，此功能应连续运行，而 SendMessage()，此功能将每周运行一次，时间由用户设置.

我想为此使用线程.

例如，用户已将时间设置为星期三4:00 pm，然后每个星期三的4:00 pm，将执行 SendMessage()，如果今天是星期五&；用户更改时间和时间从周三到周日的一天，然后在即将到来的周日应该执行...


我已经为此尝试过....

Now, I want CheckReceivedMessage(), this function should run continuously and SendMessage(), this function will run once a week which time will be set by user.

I want to use Threading for this.

For example, the user has set time Wednesday, 4:00 pm then every wednesday at 4:00 pm, SendMessage() will be executed and if today is friday & the user changes time & day from Wednesday to Sunday, then Upcoming sunday it should be executed...


And I have tried this for it....

private void Form1_Load(object sender, EventArgs e)
{
     ThreadStart thrdLoop = new ThreadStart(ThreadLoop);
     Thread thrd1 = new Thread(thrdLoop);
     thrd1.Start();
}

public void ThreadLoop()
{
     while (true)
     {
          SendMessage();
          System.Threading.Thread.Sleep(TimeSpan.FromDays(7));
     }
}

但是在上面，当用户更改时间时，以为 SendMessage()将在上次执行后7天后执行...

请为此指导我...

谢谢...

But In above, when user will change time, thought SendMessage() will execute after 7 days after last execution...

Please guide me for this...

Thank you...

推荐答案

看看石英制调度器: http ://www.quartz-scheduler.net/ [^ ]
这是一种易于使用的通用调度程序，您不必为检查时间而编写逻辑.

希望对您有所帮助.

Have a look at quartz-scheduler: http://www.quartz-scheduler.net/[^]
It''s an easy to use generic scheduler and you don not have to write logic for your time checking.

Hope it helps.

线程解决方案不是一个好主意，因为当用户重新启动计算机时，时间将会浪费.我认为另一个最佳解决方案是使用Windows Task Scheduler.只需设置时间并选择要执行的操作即可.

Thread solution is not good idea because when user restarts the computer the time will be lost. I think another best solution will be use of Windows Task Scheduler. just set time and select what should be executed.
