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(TPager pager, TEntityList entityList)
11 {
12 this .Pager = pager;
13 this .EntityList = entityList;
14 }
15 public TPager Pager { get ; set ; }
16 public TEntityList EntityList { 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 }
