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;

}
