一、NewList.aspx代码

主要是查看<div id="content_column">中的内容

二、NewList.aspx.cs代码

using CZBK.ItcastProject.Model;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace CZBK.ItcastProject.WebApp._2015_5_30{    public partial class NewList : System.Web.UI.Page    {        public string StrHtml { get; set; }        public int PageIndex { get; set; }        public int PageCount { get; set; }        protected void Page_Load(object sender, EventArgs e)        {            int pageSize=5;            int pageIndex;            if(!int.TryParse(Request.QueryString["pageIndex"],out pageIndex))            {                pageIndex=1;            }            BLL.UserInfoService UserInfoService = new BLL.UserInfoService();            int pagecount = UserInfoService.GetPageCount(pageSize);//获取总页数            PageCount = pagecount;            //对当前页码值范围进行判断            pageIndex = pageIndex < 1 ? 1 : pageIndex;            pageIndex = pageIndex > pagecount ? pagecount : pageIndex;            PageIndex = pageIndex;           List<UserInfo>list= UserInfoService.GetPageList(pageIndex,pageSize);//获取分页数据           StringBuilder sb = new StringBuilder();           foreach (UserInfo userInfo in list)           {               sb.AppendFormat("<li><span>{0}</span><a href='#' target='_blank'>{1}</a></li>",userInfo.RegTime.ToShortDateString(),userInfo.UserName);           }           StrHtml = sb.ToString();        }    }}

三、PageBarHelper.cs代码

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace CZBK.ItcastProject.Common{   public class PageBarHelper    {       public static string GetPagaBar(int pageIndex, int pageCount)       {           if (pageCount == 1)           {               return string.Empty;           }           int start = pageIndex - 5;//计算起始位置.要求页面上显示10个数字页码.           if (start < 1)           {               start = 1;           }           int end = start + 9;//计算终止位置.           if (end > pageCount)           {               end = pageCount;               //重新计算一下Start值.               start = end - 9 < 1 ? 1 : end - 9;           }           StringBuilder sb = new StringBuilder();           if (pageIndex > 1)           {               sb.AppendFormat("<a href='NewList.aspx?pageIndex={0}'>上一页</a>",pageIndex-1);           }           for (int i = start; i <= end; i++)           {               if (i == pageIndex)               {                   sb.Append(i);               }               else               {                   sb.AppendFormat("<a href='NewList.aspx?pageIndex={0}'>{0}</a>",i);               }           }           if (pageIndex < pageCount)           {               sb.AppendFormat("<a href='NewList.aspx?pageIndex={0}'>下一页</a>", pageIndex + 1);           }           return sb.ToString();       }    }}

四、pageBarStyle.css代码

page_nav{clear:both; padding:15px 0; color:#666; font:normal 12px/24px Arial; text-align:center;}.page_nav a{display:inline-block; height:22px; margin:0 2px; padding:0 8px; text-decoration:none; border:solid 1px #dbe5ee; -moz-border-radius:2px; -webkit-border-radius:2px; -khtml-border-radius:2px; border-radius:2px; background:#fff; color:#333; font:normal 12px/22px Arial, Helvetica, sans-serif; cursor:pointer;}.page_nav strong{display:inline-block; height:24px; margin:0 3px; padding:0 8px; border:none; -moz-border-radius:2px; -webkit-border-radius:2px; -khtml-border-radius:2px; border-radius:2px; background:#C00; color:#fff; font-weight:normal; line-height:24px; text-decoration:none;}.page_nav a:hover,.page_nav a.on{height:24px; margin:0 3px; border:none; background:#C00; color:#fff; line-height:24px; text-decoration:none;}.page_nav a.select{cursor:default;}.page_nav .view_all{display:block; text-align:center;}.page_nav .view_all a{height:auto; margin:0; padding:0; border:none; color:#06c; line-height:24px;}.page_nav .view_all a:hover{height:auto; margin:0; padding:0; background:none;}
