单声道Mac上的ASP.net MVC Razor视图

Question

我使用Visual Studio Community Edition for Mac创建了一个ASP.net MVC应用程序.当我运行默认的HomeController和索引视图工作正常.然后我做了一个BookController并在里面的视图中添加了一个文件夹Book和Index.cshtml文件.但是我一直收到以下错误:

System.InvalidOperationException未创建在"〜/ Views/book/Index.cshtml"中找到的视图.

描述:

HTTP 500.Error处理请求.

我用Google搜索,人们说我必须确保views文件夹中的web.config如下:

<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

这是它与system.web.mvc的版本匹配,并查看system.web.mvc内部的版本是:

5.2.3

HomeController中的默认视图有效.我是第一次在Mac上试用ASP.net MVC而且在Windows上从未遇到过这种类型的问题.

欢迎任何帮助.

更新控制器代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using TestMvcFromMac.Models;

namespace TestMvcFromMac.Controllers
{
 public class BookController : Controller
 {

    //Category category = new Category();


    public ActionResult Index()
    {
        return View ();
    }


 }
}

我猜测这个问题可能会发生，因为你正在手动创建所有的东西，而不是让模板引擎为你生成一些东西，就像在 Windows 中的 Visual Studio 中一样（个人没有尝试 Mac 版本，所以我不知道它到底是什么样子）。无论如何，假设您已经创建了控制器，然后创建了 Book 文件夹。但如果没有配置，也有一些东西需要手动配置，那就是当前控制器的路由。

您必须在RouteConfig文件类中设置路由逻辑，因此您将得到如下所示的内容：

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Book" , action = "Index", id = UrlParameter.Optional }
        );

请参阅此问题以获取更多详细信息。

我猜的另一个版本是在 return 语句本身中设置视图名称，如下所示：

return View("Index")

如果情况并非如此，请告诉我，以便我可以找到解决此问题的任何其他替代方案......
