首先得package pagedlist.mvc包，然后在action里和EF查询页里using PagedList

1.编写EF分页查询

  public IPagedList<TEntity>GetPaged(Func<TEntity,bool>where,Func<TEntity,object>order,int pageIndex,int pageSize,bool isasc)
        {
           if (isasc)
            return netDiskContext.Set<TEntity>().Where<TEntity>(where).OrderBy(order).ToPagedList(pageIndex, pageSize);
           else
               return netDiskContext.Set<TEntity>().Where<TEntity>(where).OrderByDescending(order).ToPagedList(pageIndex, pageSize);
        }

2. controll action

  public ActionResult Index(string path,int? page)
        {
            if (Session["path"] == null) Session["path"] = "\\";
            if(path!=null)
            {
                path = path.Trim()+'\\' ;
                Session["path"]=Session["path"]+ path;
            }
            int pages = page ?? 1;
            path = Session["path"].ToString();
            string currrentUser = Session["user"].ToString();
            User user=userinfo.Find(x=>x.Username==currrentUser);
            @ViewBag.filepath = Session["path"];
            IPagedList<lengxia.Model.File> ss = fileinfo.GetPaged(x => x.Belong == user.Id && x.FilePath == path,x=>x.Id, pages, 10,true);
            return View(ss);

        }

3.前端实现

@model PagedList.IPagedList<lengxia.Model.File>  
@using PagedList.Mvc;

 <table class="table table-hover">
                <tr>
                    <th>ID</th>
                    <th>文件名</th>
                    <th>文件路径</th>
                    <th>所属用户</th>
                    <th>操作</th>
                </tr>
                @foreach (var item in Model)
                {
                     <tr>
                     <th>@item.Id</th>
                         @if (@item.FileExt =="folder")
                         {
                            <td><a href="javascript:void(0)" onclick="jump(this)" id="openfolder">@item.FileName</a></td>
                         }
                         else
                         {
                             <td>@item.FileName</td>
                         }
                         <td>@item.FilePath</td>
                         <td>@item.Belong</td>
                         <td><a href="javascript:void(0)" fileid="@item.Id" onclick="tixing(this)" fileExt="@item.FileExt">删除</a>
                             /<a href="javascript:void(0)" fileid="@item.Id" onclick="rename(this)" filename="@item.FileName">修改</a></td>
                    </tr>


                }

            </table>
            @Html.PagedListPager(Model, page => Url.Action("Index",new{page}))
