好吧，您怎么知道XML已更改?它在哪里 ?如果已更改，则可以重新绑定到它.如果它是硬盘驱动器上的文件，则可以在文件更改时使用文件观察器获取报告，然后重新加载.

Well, how do you know the XML was changed ? Where is it ? If it''s changed, then you can rebind to it. If it''s a file on the hard drive, you can use a file watcher to get a report when the file is changed, and reload it.

是的.戴夫，您是对的，我们需要重新整理xml文件，
做一件事，在记事本中打开该xml文件，并根据需要进行更改，然后将其保存为相同的文件名(不要忘记再次将扩展名.xml放在同一驱动器中)，然后该系统将替换该文件，然后在运行后单击是".您的应用程序，它将起作用.
