只需將ContentType 設置為 "application/vnd.ms-excel",表示以Excel方式輸出.
代碼如下:
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 runat="server">
            <asp:GridView runat="server">
            </asp:GridView>
    </form>
</body>
</html>DataToExcel.aspx.cs

using System.Data.SqlClient;

public partial class DataToExcel : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            this.Response.ContentType = "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();
        }
    }
}
