该方法只是把asp.net页面保存成html页面只是把后缀改为xlc不过excel可以读取，接下连我看看还有别的方式能导出数据，并利用模版生成。
下面是代码
县新建一个asp.ne的tweb应用程序把代码粘贴进去就好了
html页面代码
<%@ page language=”c#” codebehind=”outexcel.aspx.cs” autoeventwireup=”false” inherits=”emeng.exam.outputexcel” %>
<!doctype html public “-//w3c//dtd html 4.0 transitional//en” >
<html>
<head>
<title>outputexcel</title>
</head>
<body>
<form id=”form1″ method=”post” runat=”server”>
<asp:datagrid id=”datagrid1″ runat=”server”>
<columns>
<asp:boundcolumn></asp:boundcolumn>
</columns>
</asp:datagrid>
<p>
<asp:label id=”label1″ runat=”server”>文件名：</asp:label>
<asp:textbox id=”textbox1″ runat=”server”></asp:textbox>
<asp:button id=”button1″ runat=”server” text=”输出到excel”></asp:button></p>
</form>
</body>
</html>
