JPager.Net MVC好用的轻量级分页控件，实现非常简单，使用也非常简单。

JPager.Net MVC好用的轻量级分页控件，代码精心推敲，经多人反复建议修改，最终成型使用中。非常好用分享给大家。源代码一共放出来。先上个效果图：

JPager.Net MVC好用的轻量级分页控件JPager.Net .dll核心代码

PagerInBase.cs

namespace JPager.Net{  /// 
  /// 分页基础类  /// 
  public class PagerInBase  {    /// 
    /// 当前页    /// 
    public int PageIndex { get; set; }    /// 
    /// 页数    /// 
    public int PageSize { get; set; }    //跳过序列中指定数量的元素    public int Skip => (PageIndex - 1) * PageSize;    /// 
    /// 请求URL    /// 
    public string RequetUrl => System.Web.HttpContext.Current.Request.Url.OriginalString;    /// 
    /// 构造函数给当前页和页数初始化    /// 
    public PagerInBase()    {      if (PageIndex == 0) PageIndex = 1;      if (PageSize == 0) PageSize = 10;    }  }}

PagerResult.cs

using System;using System.Collections.Generic;using System.Text;namespace JPager.Net{  /// 
  /// ULR拼装  /// 
  internal static class Exts  {    public static string GetUrl(this string url, int curIndex, int reps)    {      return url.Replace("pageindex=" + curIndex.ToString(), "pageindex=" + reps.ToString());    }  }  /// 
  /// 分页核心代码  /// 
  ///   public class PagerResult  {    public int Code { get; set; }    public int Total { get; set; }    public IEnumerable DataList { get; set; }         public int PageSize { get; set; }    public int PageIndex { get; set; }    public string RequestUrl { get; set; }    /// 
    /// 分页页码Html    /// 
    /// 默认样式：jpager    ///     public string PagerHtml(string cssClass="jpager")    {      if (PageIndex == 0) PageIndex = 1;      if (RequestUrl.IndexOf("?", StringComparison.Ordinal) == -1) RequestUrl += "?pageindex=1";      else      if (RequestUrl.IndexOf("&pageindex", StringComparison.Ordinal) == -1&& RequestUrl.IndexOf("?pageindex", StringComparison.Ordinal) == -1) RequestUrl += "&pageindex=1";            var html = new StringBuilder();      html.AppendFormat("", cssClass);      var pageLen = Math.Ceiling((double)Total / PageSize);      html.AppendFormat(" 首页 ", RequestUrl.GetUrl(PageIndex,1));      html.AppendFormat(" 上页 ", RequestUrl.GetUrl(PageIndex, PageIndex < 2 ? 1 : PageIndex - 1));      var si = PageIndex <= 6 ? 1 : PageIndex - 5;      var ei = si + 9;      while (si <= pageLen && si <= ei)        html.AppendFormat(          si == PageIndex            ? " {1} "            : " {1} ", RequestUrl.GetUrl(PageIndex, si), si++);      html.AppendFormat(" 下页 ", RequestUrl.GetUrl(PageIndex, (int)(PageIndex > pageLen - 1 ? pageLen : PageIndex + 1)));      html.AppendFormat(" 尾页 ",        Math.Abs(Total) <= 0         ? RequestUrl.GetUrl(PageIndex, 1)         : RequestUrl.GetUrl(PageIndex, (int) pageLen));      html.Append(@"");      return html.ToString();    }      }}

使用方法：

HomeController.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web.Mvc;using JPager.Net;using JPager.Net.Web.Models;namespace JPager.Net.Web.Controllers{  public class HomeController : Controller  {    public ActionResult Index(UserParams param)    {      //每页显示的条数默认10      //param.PageSize = 10;      //保存搜索条件      ViewBag.SearchName = param.Name;      ViewBag.SearchAge = param.Age;      //获取数据集合      var list = PageContent();       //根据条件检索      var query = param.Name!=null ?         list.Where(t=>t.Name.Contains(param.Name)).ToList() :        list.ToList();      //分页数据      var data = query.Skip(param.Skip).Take(param.PageSize);      //总页数      var count = query.Count;      var res = new PagerResult { Code = 0, DataList = data, Total = count,        PageSize = param.PageSize,PageIndex = param.PageIndex,RequestUrl = param.RequetUrl};      return View(res);    }         //测试数据                            public List PageContent()    {      var list = new List();      for (var t = 0; t < 10000; t++)      {        list.Add(new User        {          Id = t,          Name = "Joye.net"+t.ToString(),          Age = t + 10,          Score = t,          Address = "http://yinrq.cnblogs.com/",          AddTime = DateTime.Now        });      }      return list;    }  }}

Models文件夹建User.cs和UserParams.cs

User.cs

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace JPager.Net.Web.Models{  public class UserParams:JPager.Net.PagerInBase  {    public int Id { get; set; }    public string Name { get; set; }    public int ? Age { get; set; }    public int Score { get; set; }    public string Address { get; set; }    public DateTime AddTime { get; set; }  }}

UserParams.cs

using System;namespace JPager.Net.Web.Models{  public class User  {    public int Id { get; set; }     public string Name { get; set; }    public int Age { get; set; }    public int Score { get; set; }    public string Address { get; set; }    public DateTime AddTime { get; set; }  }}

view显示

@model JPager.Net.PagerResult@{  ViewBag.Title = "Index";}

      @foreach (JPager.Net.Web.Models.User item in Model.DataList)    {          }  
    
      
ID
      
Name

@item.Score
        
@item.Address

  @Html.Raw(Model.PagerHtml()) 共 @Model.Total 条
