推荐答案

看看这个线程.

http://social.msdn.microsoft.com/论坛/en-US/winforms/thread/52dcb460-90a3-45f2-ae23-bcb60514c542 [ CancelAsync 方法取消了后台工作程序.但是，辅助线程在每次更新UI线程时都会保存状态信息.这将工作进程状态"存储在主线程上.每当后台工作程序启动时，它都会简单地从状态变量中读取其信息并开始工作.

希望这对您有帮助... :)

Have a look at this thread.

http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/52dcb460-90a3-45f2-ae23-bcb60514c542[^]

The above works by saving the state information of the operation each time through its loop. When the user selects "Pause", the background worker is actually cancelled using CancelAsync method. However, the worker thread saves state information every time it updates the UI thread. This stores the "worker process state" on the main thread. Whenever the background worker is started, it simply reads its information from the state variable and goes to work.

Hope this helps... :)
