本文实例讲述了ASP.NET利用后台实现直接生成html分页的方法，是一个比较实用的功能。分享给大家供大家参考之用。具体方法如下：

1.建立存储过程：

ALTER procedure [dbo].[p_news_query]@Page intasbeginselect top 5 new_id,new_title,new_url,new_content_text,create_time,user_name from  (select *,ROW_NUMBER() over(order by new_id desc ) as RowNumber  from    (select new_id,new_title,new_url,new_content_text,        dbo.f_ConvertDate(a.create_time) create_time, b.user_name from xs_new a        left join xs_users b on b.user_no=a.create_user)TI ) A  where A.RowNumber>(@Page-1)*5end

目前实验的是每页5条数据，传入当前页码就可以了

2.前台定义一个div ，用于显示

 <div id="divPage" runat="server" class="divpage">  </div>

3.后台根据传入参数来拼html

目前是模仿博客园的模式，前后显示5条，多余的加...后到最后一条。具体代码如下：

  StringBuilder sbr = new StringBuilder();  int ITotalCount = pageLogic.QueryNewsCount();  int IPage = 1;  if (Request["p"] != null)  { IPage = Convert.ToInt32(Request["p"]);  }  int IPageCount = 5;  int ITotalPage = ITotalCount / IPageCount;  if (ITotalCount % IPageCount > 0)  { ITotalPage += 1;  }  if (IPage != 1)  { sbr.Append("<a href=/"news.ASPx?p=" + (IPage - 1).ToString() + "/"></a>");  }  if (ITotalPage <= 10)  { for (int i = 1; i <= ITotalPage; i++) {   if (i == IPage)   { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>");   }   else   { sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>");   } }  }  else  { if (IPage - 5 > 2 && IPage + 7 < ITotalPage)//前后都有的 {   sbr.Append("<a href=/"news.ASPx?p=1/">1</a>...");   for (int i = IPage - 5; i <= IPage + 5; i++)   { if (i == IPage) {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); }   }   sbr.Append("...<a href=/"news.ASPx?p=" + ITotalPage.ToString() + "/">" + ITotalPage.ToString() + "</a>"); } else if (IPage - 5 <= 2)//前面不够，后面有多余 {   for (int i = 1; i <= 10; i++)   { if (i == IPage) {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); }   }   sbr.Append("...<a href=/"news.ASPx?p=" + ITotalPage.ToString() + "/">" + ITotalPage.ToString() + "</a>"); } else if (IPage + 7 >= ITotalPage)//前面多余，后面不足 {   sbr.Append("<a href=/"news.ASPx?p=1/">1</a>...");   for (int i = ITotalPage - 10; i <= ITotalPage; i++)   { if (i == IPage) {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/" class=/"pageSelect/">" + i.ToString() + "</a>"); } else {   sbr.Append("<a href=/"news.ASPx?p=" + i.ToString() + "/">" + i.ToString() + "</a>"); }   } }  }  if (IPage != ITotalPage)  { sbr.Append("<a href=/"news.ASPx?p=" + (IPage + 1).ToString() + "/"></a>");  }  divPage.InnerHtml = sbr.ToString();  rptNews.DataSource = pageLogic.QueryNews(IPage);  rptNews.DataBind();

4.测试效果如下图所示：
