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。

代码

1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Web;
5
6 namespace System.Web.Mvc
7 {
8 public class PagerQuery < TPager,TEntityList >
9 {
10 public PagerQuery(TPagerpager,TEntityListentityList)
11 {
12 this .Pager = pager;
13 this .EntityList = entityList;
14 }
15 public TPagerPager{ get ; set ;}
16 public TEntityListEntityList{ get ; set ;}
17 }
18 }

PageInfo.cs

代码

1 using System;
2 using System.Collections.Generic;
3 using System.Linq;
4 using System.Web;
5
6 namespace System.Web.Mvc
7 {
8 public class PagerInfo
9 {
10 public int RecordCount{ get ; set ;}
11
12 public int CurrentPageIndex{ get ; set ;}
13
14 public int PageSize{ get ; set ;}
15 }
16 }

使用示例：

代码

<% @PageTitle = "" Language = " C# " MasterPageFile = " ~/Views/Shared/Site.Master " Inherits = " System.Web.Mvc.ViewPage>> " %>

< asp:ContentID = " Content1 " ContentPlaceHolderID = " TitleContent " runat = " server " >

<asp:ContentID="Content2"ContentPlaceHolderID="MainContent"runat="server">

<%foreach(variteminModel.EntityList){%>

controler：

代码

1 [AcceptVerbs(HttpVerbs.Get)]
2 public ActionResultNewsList( int boardID, int ? page)
3 {
4 PagerInfopager = new PagerInfo();
5 NewsArticleInfoinfo = new NewsArticleInfo();
