后台Controller代码

//
// GET: /Home/

public ActionResult Index(int? page)
{
 page = page ?? 1;
 PagingHelper.CurrentPage = Convert.ToInt32(page);
 PagingHelper.PageSize = 20;

 //{获取数据集的中条数，以及分页的数据集}

 PagingHelper.TotalCount = 2000;
 return View();
}

前台页面代码

@{
 ViewBag.Title = "Index";
}
@using HtmlHelperMvc.Models;
Index





 

  

   

    
    @Html.Paging(new { @class = "active" })
