ASP.NET导出数据到Excel

作者： unknow

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>
接下来是cs页面里的代码
