问题描述
我想立即通知我班级的活动订阅者.
I want to notify my class's event subscribers without delay and simultaneously.
我应该滚动我自己的事件处理程序吗?使用 FCL 中的一些支持并行性；还是默认内置的System.EventHandler<T>支持这种事件通知方式?
Should I roll my own event handler; use some from FCL supporting parallelism; or default built-in System.EventHandler<T> support such way of event notification?
推荐答案
你可以使用 MulticastDelegate.GetInvocationList 用于任何委托，然后并行调用所有组件委托.这可能是最简单的方法.
You can use MulticastDelegate.GetInvocationList for any delegate, and then just invoke all of the component delegates in parallel. That's probably the easiest way to go.
(它返回 Delegate[] 但您可以将每个实例转换为正确的类型.您甚至可以通过转换数组本身逃脱 - 我不记得它到底是哪种数组实际上创建.)
(It returns Delegate[] but you can cast each instance to the right type. You may even get away with casting the array itself - I can't remember exactly what kind of array it actually creates.)
