推荐答案

也许你正在执行的工作，在主界面线程。这将导致所有GUI事件被延迟，直到任务完成。

Probably you are performing the work in the main GUI thread. This causes all GUI events to be delayed until the task is finished.

使用一个 BackgroundWorker的代替，并使用其<一个href="http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.progresschanged.aspx"相对=nofollow> ProgressChanged 事件来更新进度条。

Use a BackgroundWorker instead and use its ProgressChanged event to update the progress bar.

还记得设置<一个href="http://msdn.microsoft.com/en-us/library/system.componentmodel.backgroundworker.workerreportsprogress.aspx"相对=nofollow> WorkerReportsProgress 以真在你的后台工作。

Also remember to set WorkerReportsProgress to true on your background worker.
