Solution 1

change row.ItemArray.All to row.ItemArray.Any

C#

dataTable = dataTable.Rows.Cast<DataRow>().Where(row =>
                    !row.ItemArray.Any(field => field is System.DBNull || string.IsNullOrEmpty(field as string))).CopyToDataTable();

thankyou for replay DamithSL , But it is not working . If i use "row.ItemArray.Any" it show an error "Object reference not set to an instance of an object."
