c# - 未找到 View 'Index' 或其母版

Question

我是 C# MVC 项目类型的新手，当我创建一个空的 C# MVC 项目时，我注意到以下错误:

The view 'Index' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/ControllerName/Index.aspx
~/Views/ControllerName/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
~/Views/ControllerName/Index.cshtml
~/Views/ControllerName/Index.vbhtml
~/Views/Shared/Index.cshtml
~/Views/Shared/Index.vbhtml

我在 Views 文件夹下有“Index.cshtml”文件。为什么MVC引擎不直接在Views文件夹下找？我该如何解决这个问题？

我的 RouteConfig.cs 内容是:

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

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

我的 Controller 内容:

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

MVC 在 vi​​ews 文件夹下寻找 View (如 Index)，但它们也必须在以其 Controller 命名的文件夹下(除了一些异常(exception)，如 partials)。

这就是您要在项目中遵循的结构

Controllers (folder)
    HomeController (.cs)
    AccountController (.cs)

Views (folder)
    Home (folder)
        Index (.cshtml)
    Account (folder)
        Index (.cshtml)
