c# - C# - How do I invoke a method on a different thread from a Timer's Elapsed event?

Question

I have a System.Timers.Timer object, and within its Elapsed method I want to call myObject.TriggerEvent(...), but I want that invocation to happen on the thread myObject was created on. Is there an easy way to do this? And is this a bad idea for any reason? myObject is basically an event manager service, so I want it to trigger events on the thread it was created on. The reason I'm using the timer is because I have another that is polling a service for updates, which it notifies myObject of via the TriggerEvent method.

Answer 1

您可以制作自己的SynchronizationContext实现并将其实例提供给myObject.TriggerEvent. 如果您myObject在 WPF、SL 或 WinForms 应用程序中使用，您可以使用它们现有的 SynchronizationContext 类实现并myObject在 GUI 线程上创建。

Answer 2

我建议使用Dispatcher。它是在 WPF 的上下文中创建的，但没有理由不能在其他地方使用它。我已经用过几次了，但我总是有一个消息泵（Win32），但我相信它也可以在服务上下文中使用（IIS 等）——但是我还没有写过这样的代码，所以YMMV。这是一篇从 WPF 角度看的好文章。
