我上网看了一下 发现他们不同的地方"好像是" 唤起的thread不同 下面是我找到的文章 When you call Control.BeginInvoke, the call to Control.Invoke is made on a threadpool thread and the call to BeginInvoke returns immediately. So, in effect, you have a worker thread calling BeginInvoke. The threadpool thread then takes over and calls Control.Invoke, waiting on the return value. The delegate passed to Invoke is then invoked on the UI thread. If you call Delegate.BeginInvoke, then you go from your worker thread to the threadpool thread, where the method pointed to by the delegate gets executed. If you are accessing UI elements on this thread, you are going to get unpredictable results. 但是我又对worker thread这个东西有点疑问 它不是UI thread，那他是什麽东西 一个windows form程式除了本身的main thread之外，背後还有一个worker thread 然後又冒出一个threadpool，这更让我想了解c#观念 越来越模糊 想请问一下各位前辈，可以指导小弟观念上的问题 谢谢各位 --
