现在有很多的xml工具软件都能根据xsd文件书写出xml文档,.net 没有实现此方法,如是我写了几个浏览、校验、和创建xml的方法
全部代码如下:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Xml.Schema;
using System.Collections;
