JPager.Net  MVC好用的轻量级分页控件，好用到你无法想象，轻量到你无法想象。

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
{
  /// <summary>
  /// 分页基础类
  /// </summary>
  public class PagerInBase
  {
    /// <summary>
    /// 当前页
    /// </summary>
    public int PageIndex { get; set; }

    /// <summary>
    /// 页数
    /// </summary>
    public int PageSize { get; set; }

    //跳过序列中指定数量的元素
    public int Skip => (PageIndex - 1) * PageSize;

    /// <summary>
    /// 请求URL
    /// </summary>
    public string RequetUrl => System.Web.HttpContext.Current.Request.Url.OriginalString;

    /// <summary>
    /// 构造函数给当前页和页数初始化
    /// </summary>
    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
{
  /// <summary>
  /// ULR拼装
  /// </summary>
  internal static class Exts
  {
    public static string GetUrl(this string url, int curIndex, int reps)
    {
      return url.Replace("pageindex=" + curIndex.ToString(), "pageindex=" + reps.ToString());
    }
  }

  /// <summary>
  /// 分页核心代码
  /// </summary>
  /// <typeparam name="T"></typeparam>
  public class PagerResult<T>
  {
    public int Code { get; set; }
    public int Total { get; set; }
    public IEnumerable<T> DataList { get; set; }     
    public int PageSize { get; set; }
    public int PageIndex { get; set; }
    public string RequestUrl { get; set; }

    /// <summary>
    /// 分页页码Html
    /// </summary>
    /// <param name="cssClass">默认样式：jpager</param>
    /// <returns></returns>
    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("<span class='{0}'>", cssClass);
      var pageLen = Math.Ceiling((double)Total / PageSize);
      html.AppendFormat("<a href='{0}'> 首页 </a>", RequestUrl.GetUrl(PageIndex,1));
      html.AppendFormat("<a href='{0}'> 上页 </a>", 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
            ? "<a style='color:black;border:none;' href='{0}'> {1} </a>"
            : "<a href='{0}'> {1} </a>", RequestUrl.GetUrl(PageIndex, si), si++);

      html.AppendFormat("<a href='{0}'> 下页 </a>", RequestUrl.GetUrl(PageIndex, (int)(PageIndex > pageLen - 1 ? pageLen : PageIndex + 1)));

      html.AppendFormat("<a href='{0}'> 尾页 </a>",
        Math.Abs(Total) <= 0 
        ? RequestUrl.GetUrl(PageIndex, 1) 
        : RequestUrl.GetUrl(PageIndex, (int) pageLen));

      html.Append(@"</span>");
      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<User> { Code = 0, DataList = data, Total = count,
        PageSize = param.PageSize,PageIndex = param.PageIndex,RequestUrl = param.RequetUrl};
      return View(res);
    }
     
 【本文转自：韩国站群服务器 欢迎转载】   //测试数据                        
    public List<User> PageContent()
    {
      var list = new List<User>();
      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<JPager.Net.Web.Models.User>
@{
  ViewBag.Title = "Index";
}

<h2>JPager.Net MVC好用的轻量级分页控件</h2>
<div>
  <div>
    <form method="get">Name：
      <input name="Name" id="Name" />
     Age：

      <input type="submit" value="查询" />
    </form>
  </div>
  <table>
    <tr>
      <th>ID</th>
      <th>Name</th>
      <th>Age</th>
      <th>Score</th>
      <th>Address</th>

    </tr>
    @foreach (JPager.Net.Web.Models.User item in Model.DataList)
    {
      <tr>
        <td>@item.Id</td>
        <td>@item.Name</td>
        <td>@item.Age</td>

        <td>@item.AddTime</td>
      </tr>
    }
  </table>

</div>
<div>
  @Html.Raw(Model.PagerHtml()) 共 @Model.Total 条

<script type="text/javascript">
  //保持搜索条件
  $(function () {
