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:

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
 {
 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>>" %>


 NewsList




 

NewsList

<% foreach (var item in Model.EntityList) { %> <% } %>
NoteID Title Author Hit ReplyNum
<%= Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) %> | <%= Html.ActionLink("Details", "NewsDetail", new { noteID=item.NoteID })%> <%= Html.Encode(item.NoteID) %> <%= Html.Encode(item.Title) %> <%= Html.Encode(item.Author)%> <%= Html.Encode(item.Hit)%> <%= Html.Encode(item.ReplyNum)%>

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

 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().GetArticleDataList(info, ArticleTypeEnum.Pass);
  pager.PageSize = 10;
  pager.CurrentPageIndex = (page!=null?(int)page:1);
  IList result = Resolve().GetArticleDataList(pager.CurrentPageIndex, pager.PageSize, ArticleTypeEnum.Pass, info);
  PagerQuery> query = new PagerQuery>(pager,result);
  return View(query);
 }
