C# 计时器是否在单独的线程上消逝? [英] Do C# Timers elapse on a separate thread?
问题描述
System.Timers.Timer 是否在与创建它的线程不同的线程上运行?
Does a System.Timers.Timer elapse on a separate thread than the thread that created it?
假设我有一个带有定时器的类,每 5 秒触发一次.当计时器触发时,在 elapsed 方法中,一些对象被修改.假设修改这个对象需要很长时间,比如 10 秒.在这种情况下,我有可能会遇到线程冲突吗?
Lets say I have a class with a timer that fires every 5 seconds. When the timer fires, in the elapsed method, some object is modified. Lets say it takes a long time to modify this object, like 10 seconds. Is it possible that I will run into thread collisions in this scenario?
推荐答案
请参阅下面布赖恩·吉迪恩 (Brian Gideon) 的回答
关于计时器的 MSDN 文档 指出:
System.Threading.Timer 类 使得ThreadPool 线程上的回调 和根本不使用事件模型.
The System.Threading.Timer class makes callbacks on a ThreadPool thread and does not use the event model at all.
因此计时器确实在不同的线程上结束.
So indeed the timer elapses on a different thread.
