i think it's hard create instance to each new line in invoice lines

for ( i = 0; i < datavalu.GetLength(0); i++)
           {
               InvoiceLine invoiceline2 = new InvoiceLine();
               invoiceline2.description = datavalu[i, 0].ToString();
               invoiceline2.itemType = datavalu[i, 1].ToString();
               invoiceline2.itemCode = datavalu[i, 2].ToString();
               invoiceline2.internalCode = datavalu[i, 3].ToString();
               invoiceline2.unitType = datavalu[i, 4].ToString();
               invoiceline2.quantity = int.Parse(datavalu[i, 5].ToString());

               invoicelines.Add(invoiceline2);


           }
