在后台线程运行定时器 [英] Run timer in background thread

问题描述

林寻找一种方式来使用一个线程的背景资料中的一个System.Windows.Forms.Timer。我CAM有很多的麻烦就来启动和后台线程内停止。这是我在做什么：

Im looking for a way to use a System.Windows.Forms.Timer within a backgrounder thread. I cam having a lot of trouble getting it to start and stop within the background thread. This is what i am doing:

private System.Windows.Forms.Timer chkTimer = new System.Windows.Forms.Timer();

然后在backgroundworker_dowork方法，我有这样的：

Then in the backgroundworker_dowork method i have this:

     chkTimer.Interval = 2000;
     chkTimer.Tick += new EventHandler(chkTimer_Tick);
     chkTimer.Start();

在蜱方法我有定时器相关的代码，但它不会出于某种原因运行。如果我宣布在上面的UI线程，它的工作原理。可以someoine请帮我启动后台线程内的计时器？我不想用这么System.Timers请不要认为

In the Tick method i have the timer related code but it will not run for some reason. If i declare the above in the ui thread, it works. Can someoine please help me start the timer within the background thread? I do not want to use System.Timers so please dont suggest that

感谢

推荐答案

我不会完全使用定时器，其微胖。从我读你想有两个线程，UI和后台线程。

I would not use a timer altogether, its extra baggage. From what I read you want to have two threads, the UI and the background thread.

所以，有后台线程管理区间，而不是定时器。

So, have the background thread manage the interval instead of the timer.

的伪代码：

YourFileChecker checker = new YourFileChecker();
checker.CheckInterval = 60000; //milliseconds, the background thread will manage the interval

System.Threading.Thread t = new System.Threading.Thread(new System.Threading.ThreadStart(checker.Check));
t.Start();

然后让检查方法做这样的事情：

Then have the Check method do something like this:

 while(!_Stop)
 {
      //Do your work here

      //Wait the specified interval before checking again...
      Thread.Sleep(_CheckInterval);
 }

后台线程现在只是不断检查，直到被告知（信号），停止。然后，你不需要计时器，因为在所有的线程管理的间隔时间。

The background thread now just keeps checking until it is told (signaled) to stop. Then you don't need the timer at all because the thread is managing the interval.
