读取文件夹下所有文件名，饼写入xml

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();
