DirectoryInfo dinfo = new DirectoryInfo(Server.MapPath("~/etao/item/")); 

       FileInfo[] files = dinfo.GetFiles("*.xml");  //读取item文件夹下所有文件名 

       FileInfo file = new FileInfo(Server.MapPath("~/etao/FullIndex.xml")); 

       XmlTextWriter textWriter = new XmlTextWriter(Server.MapPath("~/etao/FullIndex.xml"), Encoding.UTF8); 

       textWriter.WriteStartDocument(); 

       textWriter.WriteStartElement("root"); 

       textWriter.WriteElementString("version", "1.0"); 

       textWriter.WriteElementString("modified", DateTime.Now.ToString()); 

       textWriter.WriteElementString("seller_id", "官网"); 

       textWriter.WriteElementString("cat_url", config.PayUrl + "etao/SellerCats.xml"); 

       textWriter.WriteElementString("dir", config.PayUrl + "etao/item/"); 

       textWriter.WriteStartElement("item_ids"); 

       foreach (System.IO.FileInfo fi in files) 

       { 

           textWriter.WriteStartElement("outer_id"); 

           textWriter.WriteStartAttribute("action"); 

           textWriter.WriteString("upload"); 

           textWriter.WriteEndAttribute(); 

           textWriter.WriteString(fi.Name.Replace(".xml","")); 

           textWriter.WriteEndElement(); 

       } 

       textWriter.WriteEndElement(); 

       textWriter.WriteEndDocument(); 

       textWriter.Close();
