PagedList.IPaged<ProjectName.WebUI.Model>不包含配置文件的定义（您是否缺少 using 指令或引用

Question

我是 Asp.net 的新人，我有一个错误我在我的项目中使用 Pagedlist 和 ViewModel

实现了存储库模式

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace HoboAnimal.Domain.Entities
{
    public class Profile
    {

        public int ProfileID { get; set; }
        public string Color { get; set; }
        public string Image { get; set; }
        public string PlaceHolder { get; set; }
        public DateTime? DateOfPubl { get; set; }
        public string CurrentCategory { get; set; }

            }
}

我的 ViewModel class 和控制器：

using System.Collections.Generic;
using HoboAnimal.Domain.Entities;
using PagedList.Mvc;
using PagedList;

namespace HoboAnimal.WebUI.Models
{
    public class ProfilesListViewModel
    {

        public PagedList.IPagedList<Profile> Profiles {get; set;}

    }
}

和视图：

@model PagedList.IPagedList<HoboAnimal.WebUI.Models.ProfilesListViewModel>
    @using PagedList.Mvc;
    @using HoboAnimal.WebUI.Models


    <link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />
    @{
        ViewBag.Title = "Profiles";
    }


    @foreach (var p in Model.Profiles)
    {


        <h2>@p.Image</h2>
        <h3>@p.DateOfPubl</h3>
        <h2>@p.CurrentCategory</h2>

    }

Страница @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) из @Model.PageCount

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

我在这条车道上有错误：

@foreach (var p in Model.Profiles)

PagedList.IPagedList' does not contain a definition for 'Profiles' and no extension method 'Profiles' accepting a first argument of type 'PagedList.IPagedList' could be found (are you missing a using directive or an assembly reference?)

我不知道如何修复它，我尝试在我的模型中添加 @using 指令但它没有帮助谢谢你

PagedList 应该在类似于此的地方实现。无需为 PagedList 创建视图模型。

控制器

using PagedList;

public ViewResult Index(int? page)
{
   var profiles = db.Profiles.ToList();

   int pageSize = 3;
   int pageNumber = (page ?? 1);

   return View(profiles.ToPagedList(pageNumber, pageSize));
}

查看

@model PagedList.IPagedList<HoboAnimal.WebUI.Models.ProfilesListViewModel>
@using PagedList.Mvc;
@using HoboAnimal.WebUI.Models

<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />
@{
    ViewBag.Title = "Profiles";
}

@foreach (var p in Model)
{
    <h2>@p.Image</h2>
    <h3>@p.DateOfPubl</h3>
    <h2>@p.CurrentCategory</h2>
}

<br />
Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

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