Getting response when a background thread finishes its work

Question

完成后，如何从开始使用ThreadPool.QueueUserWorkItem方法的主题获得一些反馈？

Answer 1

I would recommend using a BackgroundWorker instead. That also uses the threadpool, and launches a seperate event (on the calling thread) when the background task is complete.

Otherwise you will have to do this manually by invoking a method manually on the main thread, but the BackgroundWorker encapsulates this in a very nice manner.
