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;namespace System.Web.Mvc{ public static class PagerHelper { /// <summary> /// 分页 /// </summary> /// <param name="helper"></param> /// <param name="id">分页id</param> /// <param name="currentPageIndex">当前页</param> /// <param name="pageSize">分页尺寸</param> /// <param name="recordCount">记录总数</param> /// <param name="htmlAttributes">分页头标签属性</param> /// <param name="className">分页样式</param> /// <param name="mode">分页模式</param> /// <returns></returns> public static string Pager（this HtmlHelper helper, string id, int currentPageIndex, int pageSize, int recordCount, object htmlAttributes, string className,PageMode mode） {TagBuilder builder = new TagBuilder（"table"）;builder.IdAttributeDotReplacement = "_";builder.GenerateId（id）;builder.AddCssClass（className）;builder.MergeAttributes（new RouteValueDictionary（htmlAttributes））;builder.InnerHtml = GetNormalPage（currentPageIndex, pageSize, recordCount,mode）;return builder.ToString（）; } /// <summary> /// 分页 /// </summary> /// <param name="helper"></param> /// <param name="id">分页id</param> /// <param name="currentPageIndex">当前页</param> /// <param name="pageSize">分页尺寸</param> /// <param name="recordCount">记录总数</param> /// <param name="className">分页样式</param> /// <returns></returns> public static string Pager（this HtmlHelper helper, string id, int currentPageIndex, int pageSize, int recordCount, string className） {return Pager（helper, id, currentPageIndex, pageSize, recordCount, null, className,PageMode.Normal）;

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）; }
