我已将以下nuget包添加到我的MVC 5应用程序X.PagedList.Mvc

I have added the following nuget package to my MVC 5 application X.PagedList.Mvc

我在控制器/视图中返回结果如下：

I return the results in my controller/view as follows:

// Repo public IPagedList<Post> GetPagedPosts(int pageNumber, int pageSize) { var posts = _context.Post .Include(x => x.Category) .Include(x => x.Type); // Return a paged list return posts.ToPagedList(pageNumber, pageSize); } // View model public class PostViewModel { public IPagedList<Post> Posts { get; set; } ... } // Controller method public ActionResult Index(int? page) { int pageNumber = page ?? 1; int pagesize = 5; var posts = _PostRepository.GetPagedPosts(pageNumber, pagesize); var viewModel = new PostViewModel { Posts = posts, ... }; return View(viewModel); } // View @model MyApp.ViewModels.PostViewModel @using X.PagedList.Mvc; @using X.PagedList; <p>Page @(Model.Posts.PageCount < Model.Posts.PageNumber ? 0 : Model.Posts.PageNumber) of @Model.Posts.PageCount </p>

但是在我看来，我收到以下错误 Type'IEnumerable< >'是在未引用的程序集中定义的。 System.Runtime ...

But in my view I am getting the following error The type 'IEnumerable<>' is defined in an assembly that is not referenced. System.Runtime...

我的应用程序中没有project.json文件，这是什么错误？

I have no project.json file in my application so what is this error?

推荐答案

确保Web.config文件中包含以下行：

Make sure you have the following lines in your Web.config file:

<compilation debug="true" targetFramework="4.6.1"> //don't need to change THIS line, just the content of this section <assemblies> <add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> <add assembly="System.Collections, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </assemblies> </compilation>
