.net把html页面表格转换成excel文件方法

.net把html页面表格转换成excel文件方法

一步:在页面前台加上如下代码

打  印第二步:   新建PmsAccidentStatisticsReportExcel.aspx文件.这个页面用来输出Excel文件.所以这个页面根据传过来的参数得出全部所需要下载的数据

PmsAccidentStatisticsReportExcel.aspx前台代码 (主要是建一个Table其中的每个TD用<%=_formyear%>绑定后如的string字段,用Label控件不行)

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="PmsAccidentStatisticsReportExcel.aspx.cs"
    Inherits="Web_PmsReport_Report_PmsAccidentStatisticsReportExcel" %>

   
   
   
   
   


   

        Response.AddHeader("Content-Disposition", "attachment; filename=ConsistencyAppraiseReportExcel.xls");        Response.Charset = "gb2312";        Response.ContentType = "application/msexcel";完整的代码如下
