                    {

                        excelApplication.Cells[i + 1, j + 1] = dt.Rows[i][j];

                //workbook.SaveCopyAs (filepathoutput +"\\"+ strB + ".xlsx");
                worksheet.SaveAs(filename + ".xlsx", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
                worksheet = null;
                workbook.Close(false, Missing.Value, Missing.Value);
