drXmlLink["Key"]= "";// loop thourgh and add values in to datatable
drXmlLink["Id"]= "";
dtXmlLink.Rows.Add(drXmlLink);
---end loop---

                  {
                        DataSet ds = new DataSet();
                        ds.Tables.Add(dtXmlLink );
                        MemoryStream memStream = new MemoryStream();
