Nowadays, there are many XML tool software that can write XML documents based on XSD files. .net does not implement this method. So I wrote several methods for browsing, verifying, and creating XML. The entire code is as follows:
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;
