多线程订阅同一事件 [英] Multiple Threads subscribing same event

问题描述

什么时候会发生10个线程将订阅同一事件和事件触发？
哪个线程将它捡起来？

What will happen when 10 threads will subscribe to the same event and the event fires? Which thread will pick it up?

推荐答案

线程的不订阅事件，物体做。当事件触发，所有的已注册的处理程序在同一个线程上执行（即引发事件的一种）。有没有内置工具对事件进行触发多个线程。

Thread's don't subscribe to events, objects do. When an event fires, all of the registered handlers execute on the same thread (the one that raised the event). There's no built-in facility for events to fire on multiple threads.

一个处理器可以选择将事件信息转发到一个单独的线程，如果需要的话，但是这不是一部分事件调度的内置机制。

A handler can choose to forward the event information to a separate thread, if desired, but that's not part of the built-in mechanism of event dispatch.
