This tips are used to get Mismatched records from datatable1 compared with datatable2 using LINQ Query.  This mismatched records get from another datatable.

            var exceptAB = qry1.Except(qry2);

            DataTable dtMisMatch = (from a in datatable1.AsEnumerable()
                                       join ab in exceptAB on a["ID"].ToString() equals ab.MobileNo
