以下是我在项目开发中所做的关于Excel导出功能,不足之处还望大家指正,相互学习指正

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);//文件标题 Workbook workbook = new Workbook(); //工作簿 Worksheet sheet = workbook.Worksheets[0]; //工作表 Cells cells = sheet.Cells; //单元格 //列宽 cells.SetColumnWidth(0, 20.00); cells.SetColumnWidth(1, 30.00); cells.SetColumnWidth(2, 30.00); cells.Merge(0, 0, 1, 3);//合并单元格 cells[0, 0].PutValue(title + "/文件已学人员名单"); cells[0, 1].PutValue(""); cells[0, 2].PutValue(""); cells[1, 0].PutValue("序号"); cells[1, 1].PutValue("姓名"); cells[1, 2].PutValue("时间"); 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()];//新增样式 //styleTitle.HorizontalAlignment = TextAlignmentType.Center;//文字居中 //styleTitle.Font.Name = "宋体";//文字字体 //styleTitle.Font.Size = 18;//文字大小 //styleTitle.Font.IsBold = true;//粗体 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 = "统计" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls"; string path = ConfigurationManager.AppSettings["StudyFile"] + @"/" + filename + ""; workbook.Save(path);//保存到硬盘 #region 下载 System.IO.MemoryStream ms1 = workbook.SaveToStream();//生成数据流 byte[] bt1 = ms1.ToArray(); string fileName = "统计" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";//客户端保存的文件名 //以字符流的形式下载文件 Response.ContentType = "application/vnd.ms-excel"; //通知浏览器下载文件而不是打开 Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8)); Response.BinaryWrite(bt1); Response.Flush(); Response.End(); #endregion }
