一个支持普通分页和综合分页的MVC分页Helper

本人写的一个分页helper，支持普通分页（也就是，首页、上一页、下一页、末页等），综合分页（普通分页和数字分页的综合）。

下面是分页效果：

分页代码：

pagerquery.cs包含两个属性，一个是pageinfo实体类属性pager，包含recordcount，currentpageindex，pagesize三个属性。一个是model entitylist属性。

using system;
using system.collections.generic;
using system.linq;
using system.web;

namespace system.web.mvc
{
 public class pagerquery<tpager,tentitylist>
 {
 public pagerquery(tpager pager, tentitylist entitylist)
 {
  this.pager = pager;
  this.entitylist = entitylist;
 }
 public tpager pager { get; set; }
 public tentitylist entitylist { get; set; } 
 }
}

pageinfo.cs

using system;
using system.collections.generic;
using system.linq;
using system.web;

namespace system.web.mvc
{
 public class pagerinfo
 {
 public int recordcount { get; set; }

 public int currentpageindex { get; set; }

 public int pagesize { get; set; }
 }
}

使用示例：

@ page title="" language="c#" masterpagefile="~/views/shared/site.master" inherits="system.web.mvc.viewpage<pagerquery<pagerinfo, ilist<newsarticleinfo>>>" %>

<asp:content id="content1" contentplaceholderid="titlecontent" runat="server">
 newslist
</asp:content>

<asp:content id="content2" contentplaceholderid="maincontent" runat="server">

 <h2>newslist</h2>

 <table>
 <tr>
  <th></th>
  <th>
  noteid
  </th>
  <th>
  title
  </th>
  <th>
  author
  </th>
  <th>
  hit
  </th>
  <th>
  replynum
  </th>
  
 </tr>

 <% foreach (var item in model.entitylist) { %>
 
 <tr>
  <td>
  <%= html.actionlink("edit", "edit", new { /* id=item.primarykey */ }) %> |
  <%= html.actionlink("details", "newsdetail", new { noteid=item.noteid })%>
  </td>
  <td>
  <%= html.encode(item.noteid) %>
  </td>
  <td>
  <%= html.encode(item.title) %>
  </td>
  <td>
  <%= html.encode(item.author)%>
  </td>
  <td>
  <%= html.encode(item.hit)%>
  </td>
  <td>
  <%= html.encode(item.replynum)%>
  </td>
  
 </tr>
 
 <% } %>

 </table>

 <p>
 <%=html.pager("pager",model.pager.currentpageindex,model.pager.pagesize,model.pager.recordcount,pagemode.numeric) %>
 </p>

</asp:content>

 controler：

[acceptverbs(httpverbs.get)]
 public actionresult newslist(int boardid,int? page)
 {
  pagerinfo pager = new pagerinfo();
  newsarticleinfo info = new newsarticleinfo();
  info.newsboard = new newsboardinfo();
  info.newsboard.boardid = boardid;
  pager.recordcount = resolve<inewsbll>().getarticledatalist(info, articletypeenum.pass);
  pager.pagesize = 10;
  pager.currentpageindex = (page!=null?(int)page:1);
  ilist<newsarticleinfo> result = resolve<inewsbll>().getarticledatalist(pager.currentpageindex, pager.pagesize, articletypeenum.pass, info);
  pagerquery<pagerinfo, ilist<newsarticleinfo>> query = new pagerquery<pagerinfo, ilist<newsarticleinfo>>(pager,result);
  return view(query);
 }
