解决方案

为了更新进度条，您需要执行此操作另一个线程中的副本 - 或复制操作阻止UI被更新。

最简单的方法是使用BackgroundWorker - 它允许你做的工作的肉一个线程，并提供显示进度的事件： BackgroundWorker Class （System.ComponentModel） [ ^ ]

解决方案

In order to update a progress bar, you need to do the copy in a different thread - or the copy operation prevents the UI being updated.
The easiest way to handle that is to use a BackgroundWorker - it allows you to do the "meat" of the job in one thread, and provides events to show the progress: BackgroundWorker Class (System.ComponentModel)[^]
