This method only saves the asp.net page as an html page. It only changes the suffix to xlc, but it can be read in excel. Next, let's take a look at other ways to export data and generate it using templates.
Below is the code
Create an asp. ne tweb application in the county and paste the code.
Html page code
<% @ 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"> file name: </asp: Label>
<Asp: TextBox id = "TextBox1" runat = "server"> </asp: TextBox>
<Asp: button id = "Button1" runat = "server" Text = "output to Excel"> </asp: button> </P>
</Form>
</Body>
</HTML>
Next is the code on the cs page.
