推荐答案

解决此问题的标准方法是使用标准(WinForms?WPF?)进度栏.在单独的线程中启动冗长的操作(使用Thread.Start，BackgroundWorkerThread或Task，在该操作上发出进度事件的信号，并让UI类(可能是您的主窗体)订阅进度事件以更新进度栏.将在操作线程上引发，您将需要使用Invoke或BeginInvoke将对进度条控件的更新封送回UI线程.

The standard approach to this is to use the standard (WinForms? WPF?) progress bar. Start the lengthy operation in a separate thread (using Thread.Start, BackgroundWorkerThread or Task, signal progress events on the operation, and have the UI class (probably your main form) subscribe to the progress event to update the progress bar. Since the event will be raised on the operation thread, you will need to use Invoke or BeginInvoke to marshal the update to the progress bar control back to the UI thread.
