1、前台界面

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="练习.WebForm1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
 <title></title>
   <style type="text/css">
   #mydiv ul{ list-style-type:none;}
   #mydiv ul li{ display:inline;}
   #mydiv{ width:500px; border:solid 1px #444; background-color:#333;} 
   </style>
   <link href="css/nf.lightbox.css" rel="stylesheet" type="text/css" />
   <script src="Jquery1.7.js" type="text/javascript"></script>
   <script src="js/NFLightBox.js" type="text/javascript"></script>
   <script type="text/javascript">
    $(function () {
     //var settings = { containerResizeSpeed: 3000 };
     $('#mydiv ul a').lightBox({ containerResizeSpeed: 1000 });
    })
  
   </script>
</head>
<body>
<form id="form1" runat="server">
 <div id="mydiv" runat="server">
 
 </div>
 </form>

</body>
</html>

2、后台代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.Text;

namespace 练习
{
 public partial class WebForm1 : System.Web.UI.Page
 {
  protected void Page_Load(object sender, EventArgs e)
  {

   if (!IsPostBack)
   {
    LoadData();
   }
  }
 private void LoadData() 
  {
   string constr = "data source=LOVE-PC\\SQLEXPRESSPC;initial catalog=BoKe;user id=sa;password=admin";
   using (SqlConnection conn = new SqlConnection(constr))
   {
    using (SqlCommand cmd =conn.CreateCommand())
    {
     conn.Open();
     cmd.CommandText = "select BigImgUrl,SmallImgUrl from T_Photo";
     SqlDataAdapter adapter = new SqlDataAdapter(cmd);
     DataTable dt = new DataTable();
     adapter.Fill(dt);
     StringBuilder sb = new StringBuilder();
     sb.Append("<ul>");
     for (int i = 0; i < dt.Rows.Count; i++)
     {
      sb.Append("<a href=" + dt.Rows[i]["BigImgUrl"] + ">");//添图片路径
      sb.Append("<li>");
      sb.Append("<img src=" + dt.Rows[i]["SmallImgUrl"] + ">");//添图片路径
      sb.Append("</li>");
      sb.Append("</a>");


     }
     sb.Append("</ul>");
      mydiv.InnerHtml = sb.ToString();
    }
   }
   
  }
 }
}
