只需将ContentType 设置为 "application/vnd.ms-excel",表示以Excel方式输出.
代码如下:
DataToExcel.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DataToExcel.aspx.cs" Inherits="DataToExcel" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>DataToExcel</title>
</head>
<body>
    <form id="form1" runat="server">
            <asp:GridView ID="GridView1" runat="server">
            </asp:GridView>
    </form>
</body>
</html>DataToExcel.aspx.cs
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;

public partial class DataToExcel : System.Web.UI.Page
"application/vnd.ms-excel";
            string ConnStr = "server=localhost;uid=sa;pwd=;database=northwind";
            SqlConnection Conn = new SqlConnection(ConnStr);
            Conn.Open();
            string sqlcmd = "select lastname,firstname,title, address, city from employees";
            SqlCommand cmd = new SqlCommand(sqlcmd, Conn);
            SqlDataAdapter adapter = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            adapter.Fill(ds);
            this.GridView1.DataSource = ds.Tables[0].DefaultView;
            this.GridView1.DataBind();
        }
    }
}
