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：

PagerHelper.cs

using System.Collections.Generic; using System.Collections.Specialized; using System.Linq; using System.Web; using System.Text; using System.Web.Mvc; using System.Web.Routing; using System.Data.Objects.DataClasses;

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。
