.NET 定时器异步运行吗? [英] Do .NET Timers Run Asynchronously?

问题描述

我使用 Jabber-net(<一个 href="http://en.wikipedia.org/wiki/List_of_XMPP_library_software" rel="noreferrer">XMPP 库.)

如果由于某种原因与服务器的连接终止，我想做的是每隔一分钟左右尝试连接一次.

What I would like to do, if for some reason the connection to the Server is ended, is keep trying to connect every minute or so.

如果我启动一个计时器以在下一次尝试之前等待一段时间，该计时器是否异步运行并且产生的 Tick 事件加入主线程，或者我是否需要启动我自己的线程并从内部启动计时器在那里?

If I start a Timer to wait for a period of time before the next attempt, does that timer run asynchronously and the resulting Tick event join the main thread, or would I need to start my own thread and start the timer from within there?

推荐答案

你使用的是哪种定时器?

What kind of timer are you using?

• System.Windows.Forms.Timer 将在 UI 线程中执行
• System.Timers.Timer 在线程池线程中执行，除非您指定 SynchronizingObject
• System.Threading.Timer 在线程池线程中执行其回调

• System.Windows.Forms.Timer will execute in the UI thread
• System.Timers.Timer executes in a thread-pool thread unless you specify a SynchronizingObject
• System.Threading.Timer executes its callback in a thread-pool thread

在所有情况下，定时器本身都是异步的——它不会占用"一个线程，直到它被触发.

In all cases, the timer itself will be asynchronous - it won't "take up" a thread until it fires.
