Repeater、GridView等 操作XML文件
在项目中需要对XML文件进行管理，我用了Repeater 的方式来实现了实时的更新
希望对阅读这篇随笔的您有所帮助,我用的Repeater,您也可以用GridView等...区别仅仅在于控件内的按钮的事件中获取当前操作对象索引的方式..
如果您的XML文档格式与此不同,建议使用下面的XML格式（因为这个格式能够通过DataSet的LoadXML方法直接获得数据源，并且能够使用DateSet的WriteXML方法输出XML文档）或者您可以根基自己的格式重新写ReadXmlInfo和WriteXMLInfo这两个方法。
首先是我的XML格式
代码
