ASP.NET技巧:数据岛出到Excel最为简易的方法

  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

  {

  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();

  }

  }

  }
