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

1usingSystem;
2usingSystem.Collections.Generic;
3usingSystem.Linq;
4usingSystem.Web;
5
6namespaceSystem.Web.Mvc
7{
8publicclassPagerQuery<TPager,TEntityList>
9{
10publicPagerQuery(TPagerpager,TEntityListentityList)
11{
12this.Pager=pager;
13this.EntityList=entityList;
14}
15publicTPagerPager{get;set;}
16publicTEntityListEntityList{get;set;}
17}
18}

PageInfo.cs

代码

1usingSystem;
2usingSystem.Collections.Generic;
3usingSystem.Linq;
4usingSystem.Web;
5
6namespaceSystem.Web.Mvc
7{
8publicclassPagerInfo
9{
10publicintRecordCount{get;set;}
11
12publicintCurrentPageIndex{get;set;}
13
14publicintPageSize{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">

tr>

<%foreach(variteminModel.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>

tr>

<%}%>

table>

<p>
<%=Html.Pager("pager",Model.Pager.CurrentPageIndex,Model.Pager.PageSize,Model.Pager.RecordCount,PageMode.Numeric)%>
p>

asp:Content>

controler：

代码

1[AcceptVerbs(HttpVerbs.Get)]
2publicActionResultNewsList(intboardID,int?page)
3{
4PagerInfopager=newPagerInfo();
5NewsArticleInfoinfo=newNewsArticleInfo();

10pager.CurrentPageIndex=(page!=null?(int)page:1);
11IList<NewsArticleInfo>result=Resolve<INewsBLL>().GetArticleDataList(pager.CurrentPageIndex,pager.PageSize,ArticleTypeEnum.Pass,info);
12PagerQuery<PagerInfo,IList<NewsArticleInfo>>query=newPagerQuery<PagerInfo,IList<NewsArticleInfo>>(pager,result);
