asp.net excel導出功能 TOP

以下是我在項目開發中所做的關于Excel導出功能，不足之處還望大家指正，相互學習指正
protected void btn_Export_Click(object sender, EventArgs e)
    {
        string FileID = "";
        if (Request.QueryString["fujian"] != null && Request.QueryString["fujian"].ToString() != "")
        {
            FileID = Request.QueryString["fujian"].ToString();
        }
        string title = GetFileTile(FileID);//文件標題
        Workbook workbook = new Workbook(); //工作簿
        Worksheet sheet = workbook.Worksheets[0]; //工作表
        Cells cells = sheet.Cells; //單元格        
        //列寬
        cells.SetColumnWidth(0, 20.00);
        cells.SetColumnWidth(1, 30.00);
        cells.SetColumnWidth(2, 30.00);
        cells.Merge(0, 0, 1, 3);//合并單元格
 
        cells[0, 0].PutValue(title + "/文件已學人員名單");
        cells[0, 1].PutValue("");
        cells[0, 2].PutValue("");
        cells[1, 0].PutValue("序號");
        cells[1, 1].PutValue("姓名");
        cells[1, 2].PutValue("時間");
        string sql = "order by StudyTime";
        ds = PublishBLL.GetCommentCount(FileID, sql);
        if (ds.Tables[0].Rows.Count > 0)
        {
 
            for (int i = 1; i < ds.Tables[0].Rows.Count + 1; i++)
            {
                //Aspose.Cells.Style styleTitle = workbook.Styles[workbook.Styles.Add()];//新增樣式
                //styleTitle.HorizontalAlignment = TextAlignmentType.Center;//文字居中
                //styleTitle.Font.Name = "宋體";//文字字體
                //styleTitle.Font.Size = 18;//文字大小
                //styleTitle.Font.IsBold = true;//粗體
                cells[i + 1, 0].PutValue("" + i.ToString().PadLeft(3, ''0'') + "");
                cells[i + 1, 1].PutValue("" + ds.Tables[0].Rows[i - 1]["StudyName"].ToString() + "");
                cells[i + 1, 2].PutValue("" + ds.Tables[0].Rows[i - 1]["StudyTime"].ToString() + "");
            }
        }
        string filename = "統計" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";
        string path = ConfigurationManager.AppSettings["StudyFile"] + @"\" + filename + "";
        workbook.Save(path);//保存到硬盤
 
        #region 下載
        System.IO.MemoryStream ms1 = workbook.SaveToStream();//生成數據流
        byte[] bt1 = ms1.ToArray();
        string fileName = "統計" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";//客戶端保存的文件名
        //以字符流的形式下載文件
        Response.ContentType = "application/vnd.ms-excel"; //通知瀏覽器下載文件而不是打開
 
        Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
        Response.BinaryWrite(bt1);
        Response.Flush();
        Response.End();
        #endregion
