c# – 单声道Mac上的ASP.net MVC Razor视图

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 The view found at
‘~/Views/book/Index.cshtml’ was not created.

描述：

HTTP 500.Error processing request.

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 ();
    }


 }
}

解决方法

我猜测问题可能会发生,因为你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,如在Windows中的visual studio(个人没有尝试Mac版本所以我不知道它究竟是怎么样的).无论如何,假设您已经创建了控制器,然后创建了Book文件夹.但是如果没有配置,还有手动配置的东西,那就是当前控制器的路由.

你必须在RouteConfig文件类中设置路由逻辑,所以你会有这样的东西：

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

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

有关详细信息,请参阅此问题here.

我猜的另一个版本是在return语句中设置视图名称,如下所示：

return View("Index")

如果不是这种情况,请告诉我,以便我可以看到此问题的任何其他替代方案……
