Convert Dataset to XML

Question

I\'ve been stuck with this problem for a few hours and can\'t seem to figure it out, so I\'m asking here :)

Alright, I\'ve got this function:

private

Try this. It worked for me.

static XmlDocument xdoc = new XmlDocument(); //static; since i had to access this file someother place too
protected void CreateXmlFile(DataSet ds) 
    {
      //ds contains sales details in this code; i.e list of products along with quantity and unit
      //You may change attribute acc to your needs ; i.e employee details in the below code

        string salemastid = lbl_salemastid.Text;
        int i = 0, j=0;
        String str = "salemastid:" + salemastid;
        DataTable dt = ds.Tables[0];
        string xml = "<Orders>" ;
         while (j < dt.Rows.Count)
         {
             int slno = j + 1;
             string sl = slno.ToString();
             xml += "<SlNo>" + sl +"</SlNo>" +
                       "<PdtName>" + dt.Rows[j][0].ToString() + "</PdtName>" +
                       "<Unit>" + dt.Rows[j][1].ToString() + "</Unit>" +
                       "<Qty>" + dt.Rows[j][2].ToString() + "</Qty>";
             j++;
         }
         xml += "</Orders>";

         xdoc.LoadXml(xml);
         //Here the xml is prepared and loaded in xml DOM.

         xdoc.Save(Server.MapPath("Newsales.xml"));
         //You may also use some other names instead of 'Newsales.xml'

         //to get a downloadable file use the below code
         System.IO.MemoryStream stream = new System.IO.MemoryStream();
                XmlTextWriter xwriter = new XmlTextWriter(stream, System.Text.Encoding.UTF8);

                xdoc.WriteTo(xwriter);
                xwriter.Flush();
                Response.Clear();
                Encoding.UTF8.GetString(stream.ToArray());
                byte[] byteArray = stream.ToArray();
                Response.AppendHeader("Content-Disposition", "filename=OrderRequest.xml");
                Response.AppendHeader("Content-Length", byteArray.Length.ToString());
                Response.ContentType = "application/octet-stream";
                Response.BinaryWrite(byteArray);
                xwriter.Close();
                stream.Close();

        }
