1.框架是.NET Framework 4.0
2.一共为三个部分: 前台页面设计代码、前台页面程序代码、css样式
3.其中数据库连接操作用了DB类(连接语句),SQLHelper(微软的数据库操作类)
效果图:

  前台页面程序代码

using System.Collections.Generic;
using System.Linq;

using System.Web.UI.WebControls;
using TestWebSite.Utilities;
using System.Data;
using System.Data.SqlClient;
using Wuqi.Webdiyer;

namespace TestWebSite
{
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //调用绑定分页和GridView
                BindGridView();

            pds.CurrentPageIndex = AspNetPager1.CurrentPageIndex - 1;
            //设置每页显示页数

            pds.AllowPaging = true;
            //设置GridView的数据源为分页数据源
            GridView1.DataSource = pds;
            //绑定GridView
            GridView1.DataBind();
        }

        protected void AspNetPager1_PageChanged(object sender, EventArgs e)

}

  CSS样式
.anpager
{
    font: 11px Arial, Helvetica, sans-serif;
    padding:10px 20px 10px 0;
    margin: 0px;
}
.anpager a
{
    padding: 1px 6px;
    border: solid 1px #ddd;
    background: #fff;
    text-decoration: none;
    margin-right:2px
}
.anpager a:visited
{
    padding: 1px 6px;
    border: solid 1px #ddd;
    background: #fff;
    text-decoration: none;
}
.anpager .cpb
{
    padding: 1px 6px;
    font-weight: bold;
    font-size: 13px;
    border:none
}
.anpager a:hover
{
    color: #fff;
    background: #ffa501;
    border-color:#ffa501;
    text-decoration: none;
}

/* AspNetPager1属性设置: CssClass="anpager" CurrentPageButtonClass="cpb"*/

 code in my life.
