    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);
        }
        //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>

        <form method="get">Name:

        </tr>
        @foreach (JPager.Net.Web.Models.User item in Model.DataList)

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