背景Controller代码

//
// GET: /Home/

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

 //{猎取数据集的中条数，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;
<h2>Index</h2>
<hr />
<style type="text/css">
 #on
 {
  color: #FFF;
  background-color: #337AB7;
  border-color: #337AB7;
 }

 .pagination a
 {
  margin-right: 3px;
  padding: 5px 10px;
  font-size: 12px;
  text-decoration: none;
  background-color: #fff;
  border: 1px solid #ddd;
  cursor: pointer;
  display: inline-block;
  border-radius: 3px;
 }

 a
 {
  color: #337ab7;
  text-decoration: none;
 }

 a
 {
  background-color: transparent;
 }

 *
 {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
 }
</style>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script type="text/javascript">
 $(function () {
  $(".pagination .active").live("click", function () {
   $("#page").val($(this).attr("page"));
   $("#form_Submit").submit();
  });
 });
</script>
<form id="form_Submit" action="/Home/Index" method="post">
 <p class="fix">
  <p class="page">
   <p class="pagination pagination-sm pull-right" id="pagep" style="margin: 0px 0;">
    <input type="hidden" id="page" name="page" value="@PagingHelper.CurrentPage" />
    @Html.Paging(new { @class = "active" })
   </p>
  </p>
 </p>
</form>
