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

问题描述

我有我的应用程序中使用的Jabber网一个消息方面，（一的 XMPP库。）

I have a messaging aspect of my application using Jabber-net (an XMPP library.)

我想这样做，如果由于某种原因连接到服务器端，是不断尝试每分钟左右进行连接。

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.

如果我启动一个定时器等待一段时间，下一个尝试之前，这是否定时器异步运行，所得Tick事件加盟为主线，或者我需要开始自己的线程，并从内部启动定时器在那里？

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

您使用的是什么样的计时器？

What kind of timer are you using?

• System.Windows.Forms.Timer 将在UI线程中执行
• System.Timers.Timer的在一个线程池线程执行，除非你指定一个 SynchronizingObject的
• System.Threading.Timer 在一个线程池线程执行其回调

• 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

在所有的情况下，定时器本身将是异步 - 它不会占用一个线程，直到它触发

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