Aspose.Cells 根据Excel模板导出数据统计

如最近公司项目中用到数据统计出Excel报表，从博客园找了相关的文章，第一次用到了Aspose.Cells，听说很强大。因为技术很菜，学习别的大牛的博客文章捣鼓了好久才搞出来，记录一下备忘。呵呵~

    using Aspose.Cells;//Aspose.Cells引入的命名空间
    /// <summary>
    /// 导出报表
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void imgbtnExportExcel_Click(object sender, ImageClickEventArgs e)
    {
            DataTable dt = helper.ExecuteDataTable(querySql);
            dt.TableName = "A";
            if (dt.Rows.Count == 0)
                return;


            WorkbookDesigner designer = new WorkbookDesigner();
          
            //Server.MapPath("./")  
            string path = System.IO.Path.Combine(Server.MapPath("./"), "Templete/book1.xls");
            designer.Open(path);
            designer.SetDataSource(dt);
           

            designer.Process();

            //Save the excel file
            string fileToSave = System.IO.Path.Combine(Server.MapPath("./"), "Templete/JH_ManageExcel.xls");
            if (File.Exists(fileToSave))
            {
                File.Delete(fileToSave);
            }

            designer.Save(fileToSave, FileFormatType.Excel2003);
            //打开Excel文件
            Process.Start(fileToSave);
}

    sqlhelper.cs     public DataSet ExcuteDataSet(string sql)
    {
        SqlConnection con = new SqlConnection(connectionString);

        con.Open();
        SqlDataAdapter dr = new SqlDataAdapter(sql, con);
        DataSet ds = new DataSet();
        dr.Fill(ds);
        con.Close();
        return ds;
       
        
    }
*****************************************第二种写法********************************出现保存窗口提示用户保存
  DataTable dt = helper.ExecuteDataTable(querySql);
            dt.TableName = "A";
            if (dt.Rows.Count == 0)
                return;
            WorkbookDesigner designer = new WorkbookDesigner();
            designer.Open(MapPath("~/Templete/book1.xls"));
            designer.SetDataSource(dt);
            designer.Process();             
            designer.Save(string.Format("JH-report.xls"), SaveType.OpenInExcel, FileFormatType.Excel2003, Response);
            Response.Flush();
            Response.Close();
            designer = null;
            Response.End();

自己建立一个兼容excel 模板，写好样式，填好公式。

效果如下：
