                }

                sw.Write("\r\n");

                sw.Flush();
                sw.Close();

                MessageBox.Show("成功匯出[" + myDataTable.Rows.Count.ToString() + "]行到Execl!");
            }
            catch (Exception ex)
            {
                MessageBox.Show("匯出Execl失敗!");
            }
