您好，这个源码是我根据网上一个vb.net编辑xml文件的原理用c#重写的。除重用xml文件外.并未重用任何代码！.这小段代码，可对xml文件的记录进行删除，修改，或增加新记录。利用了datagrid控件的sortcommand事件对xml里的记录进行排序。email:ouyang76.263.net------------------------------------------< %@page language="c#" Trace="true"%><%@import namespace="System.Data"%><%@import namespace="System.IO"%><script language="c#" runat="server">string xmlfile="books2.xml",xpath;void page_load(Object obj,EventArgs e){xpath=Server.MapPath(xmlfile);
