未找到“报告”视图或其主视图，或者没有视图引擎支持搜索的位置

Question

我已经四处搜索了几天，似乎找不到适合我的问题的解决方案。我很确定它与路由有关，但我不确定。

我收到的确切错误是：

The view 'Reporting' or its master was not found or no view engine supports the searched locations. The following locations were searched:

我的 Web 应用程序中的每个页面都出现此错误，但是无论我使用 URL 还是键入 /Home/Index，我的主页都能正常工作。

我的控制器内部方法名称与我的视图名称匹配

public ActionResult Reporting()
    {
        var model = new DashboardCurrentRelease
        {
            ApplicationNames = GetApplications()
        };

        return View("Reporting", (object)model);
    }

GetApplications() 方法如下所示：

private IEnumerable<SelectListItem> GetApplications()
        {
            var applications = new DashboardViewModel();
            var applicationList = applications.DashboardCurrentReleases.Select(x => new SelectListItem
            {
                Value = x.ApplicationName.ToString(),
                Text = x.ApplicationName
            });

            return new SelectList(applicationList, "Value", "Text");
        }

这是我的模型的样子：

public partial class DashboardViewModel : DbContext
    {
        public DashboardViewModel()
            : base("name=DashboardViewModel1")
        {
        }

        public virtual DbSet<DashboardCurrentRelease> DashboardCurrentReleases { get; set; }

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<DashboardCurrentRelease>()
                .Property(e => e.ApplicationName)
                .IsUnicode(false);

            modelBuilder.Entity<DashboardCurrentRelease>()
                .Property(e => e.Release)
                .IsUnicode(false);
        }
    }

[Table("DashboardCurrentRelease")]
    public partial class DashboardCurrentRelease
    {
        [Display(Name = "Application Name")]
        public IEnumerable<SelectListItem> ApplicationNames { get; set; }

        [Key]
        [Column(Order = 0)]
        [DatabaseGenerated(DatabaseGeneratedOption.None)]
        public int ApplicationKey { get; set; }

        [StringLength(50)]
        public string ApplicationName { get; set; }

        [StringLength(50)]
        public string Release { get; set; }

        public int? FailCnt { get; set; }

        public int? PassCnt { get; set; }

        public int? OtherCnt { get; set; }

        public int? ExecutedCnt { get; set; }

        public int? NotExecutedCnt { get; set; }
    }

我的 routingconfig 文件如下所示：

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

对如何解决我的问题有任何想法吗？我没有正确执行我的 RouteConfig 吗？我读到它必须首先是最不具体的路线，然后是最具体的路线，但它仍然不想为我工作。

另外一个我试过但没有成功的Route Config也是这样的：

public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute("Reporting", "{controller}/{action}",
            new
            {
                controller = "Reporting",
                action = "Reporting"
            });

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

我应该提到，我已将每个视图页面的所有属性设置为内容的构建操作，之前它们是“无”，但这也没有解决问题。

编辑： 我忘了提一下，当我在本地环境中调试时它工作得非常好，当它尝试在网络服务器上运行时它开始中断。

编辑 2：我已将堆栈跟踪添加到我最初的问题以及模型和一些修饰。

编辑 3：最后一件事是，为了访问我尝试以 2 种不同方式从视图执行此操作的页面。第一种方法是：

@Html.ActionLink("Report Details", "Reporting", "Reporting")

第二个在做：

<a href="../Reporting/Reporting">
                                        <span>Report Details</span>
                                    </a>

Answer 1

在MVC中，用于解析传入和传出URL组合的路由引擎，如果遵循路由引擎使用的约定（规则），则不必更改配置。我真的只对 MVC 约定之外的区域或任何内容使用自定义路由。而且您的约定似乎遵循 MVC 的指导方针，文件夹和控制器相互匹配。所以我认为您不需要自定义路线。

ASP.net MVC 的路由引擎不提供网页 (.cshtml)。它提供了一种由代码中的类处理 URL 的方法，该类可以将 text/html 呈现到输出流，或者使用约定以一致的方式解析和提供 .cshtml 文件。您的视图引擎是从以控制器命名的目录中提供网页 (.cshtml) 文件的引擎。这就是说路由引擎控制 URL。你试过**return View("NameOfView", Model);**

您需要注意其他事情，例如确保命名空间正确，以及您是否从模型中获取字符串？你们中的它必须像return View("Message",(object)msg);而不是return View("Message",msg);这样正确格式化，因为我看不到您的模型或您的视图，并且没有发布完整的堆栈跟踪，很难说为什么您的视图没有显示。当然，如果您显示一个正在以更改名称调用的 URL，那也很好。但我能想到的主要是模型和/或命名空间，此外，如果您从视图中调用 Layout = "~/Views/Shared/_Layout.cshtml"; 或者您是否依赖于 _ViewStart 文件。还要检查您是否从菜单或链接中调用了正确的操作。 @Html.Action 方法实际上调用了一个控制器并呈现视图，您是否尝试使用智能感知来查看 ActionLink 的重载（@Html.ActionLink("Some text","Action","Controller", new {id=1}, null)），只是为了确保您从链接调用正确的操作。希望这种方式可以为您指明解决方案的正确方向。
