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{    ///     /// 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

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; }    }}

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";}

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