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

<?xml version="1.0" standalone="yes"?>
<imgs>
  <pic name="/adv_pic/1.jpg" url="http://www.baidu.com/" title="美国影视中的黑人总统盘点" />
  <pic name="/adv_pic/2.jpg" url="http://www.baidu.com/" title="斯琴格日乐--我很好！" />
  <pic name="/adv_pic/3.jpg" url="http://www.baidu.com/" title="伦敦金融城市长秀" />
  <pic name="/adv_pic/4.jpg" url="http://www.baidu.com/" title="市长大人的金色大马车" />
  <pic name="/adv_pic/5.jpg" url="http://www.baidu.com/" title="英国皇家歌剧院艺术家为公益缘何全裸？" />
</imgs>

HTML Code：

</html>

然后贴C# code

使用的是Anthem控件,不使用Anthem控件的朋友可以使用常规控件,不影响效果
