Question

我需要一些路由帮助。我试图找到现有的问题 - 答案，但没有任何帮助我。如果已经有答案，请链接。

我的结构：

/Controller
--/Root
----/HomeController.cs
/Views
--/Root
----/Home
------/Index.cshtml

问题是，无法找到Index.cshtml。

视图＆＃39;索引＆＃39;或者找不到它的主人。以下地点   被搜查了：

〜/查看/主页/的Index.aspx
  〜/浏览/首页/ Index.ascx
  〜/ Views / Shared / Index.aspx
  〜/查看/共享/ Index.ascx
  〜/ Views / Home / Index.cshtml
  〜/浏览/首页/ Index.vbhtml
  〜/ Views / Shared / Index.cshtml
  〜/ Views / Shared / Index.vbhtml

堆栈跟踪：

System.Web.Mvc.ViewResult.FindView（ControllerContext context）+382 System.Web.Mvc.ViewResultBase.ExecuteResult（ControllerContext context）+116 System.Web.Mvc.ControllerActionInvoker.InvokeActionResult（ControllerContext controllerContext，ActionResult actionResult）+13 System.Web.Mvc。＆lt;＆gt; c__DisplayClass1a.b__17（）+23 System.Web.Mvc.ControllerActionInvoker.InvokeActionResultFilter（IResultFilter过滤器，ResultExecutingContext preContext，Func 1 continuation) +245<br /> System.Web.Mvc.<>c__DisplayClass1c.<InvokeActionResultWithFilters>b__19() +22 System.Web.Mvc.ControllerActionInvoker.InvokeActionResultWithFilters(ControllerContext controllerContext, IList 1过滤器，ActionResult actionResult）+176 System.Web.Mvc.Async。＆lt;＆gt; c__DisplayClass2a.b__20（）+75 System.Web.Mvc.Async。＆lt;＆gt; c__DisplayClass25.b__22（IAsyncResult asyncResult）+99 System.Web.Mvc.Async.WrappedAsyncResult 1.End() +50 System.Web.Mvc.Async.AsyncControllerActionInvoker.EndInvokeAction(IAsyncResult asyncResult) +27 System.Web.Mvc.<>c__DisplayClass1d.<BeginExecuteCore>b__18(IAsyncResult asyncResult) +14 System.Web.Mvc.Async.<>c__DisplayClass4.<MakeVoidDelegate>b__3(IAsyncResult ar) +16 System.Web.Mvc.Async.WrappedAsyncResult 1.End（）+50 System.Web.Mvc.Controller.EndExecuteCore（IAsyncResult asyncResult）+36 System.Web.Mvc.Async。＆lt;＆gt; c__DisplayClass4.b__3（IAsyncResult ar）+16 System.Web.Mvc.Async.WrappedAsyncResult 1.End() +50 System.Web.Mvc.Controller.EndExecute(IAsyncResult asyncResult) +26 System.Web.Mvc.Controller.System.Web.Mvc.Async.IAsyncController.EndExecute(IAsyncResult asyncResult) +10 System.Web.Mvc.<>c__DisplayClass8.<BeginProcessRequest>b__3(IAsyncResult asyncResult) +25 System.Web.Mvc.Async.<>c__DisplayClass4.<MakeVoidDelegate>b__3(IAsyncResult ar) +16 System.Web.Mvc.Async.WrappedAsyncResult 1.End（）+50 System.Web.Mvc.MvcHandler.EndProcessRequest（IAsyncResult asyncResult）+28 System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.EndProcessRequest（IAsyncResult result）+9 System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute（）+9721605 System.Web.HttpApplication.ExecuteStep（IExecutionStep step，Boolean＆amp; completedSynchronously）+155

路由是这样的：

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

我错过了什么吗？

默认情况下，MVC在~/Views/YourControllerName文件夹中查找视图。看起来您的控制器和视图有一个名为root的目录。我不确定你为什么要那样做。如果您这样做是为了在项目中逻辑地组织代码，您应该考虑Areas。

您可以创建一个名为root的新区域。这将在~/Areas下创建一个名为root的目录。您可以在其下创建控制器和视图。当您定义路线时，您不需要在您的网址中包含单词Root，因为您将有一个区域注册以单词Root（您可以自定义）开始

但是，如果您真的不想使用区域，但希望将视图保留在~/Views/root目录下，则可以创建自定义视图引擎并指定查找视图文件的位置。

public class MyCustomViewEngine : RazorViewEngine
{
    public MyCustomViewEngine()
    {
        string[] viewLocationFormatArr=new string[4];
        viewLocationFormatArr[0] = "~/Views/root/{1}/{0}.cshtml";
        viewLocationFormatArr[1] = "~/Views/Root/{1}/{0}.vbhtml";
        viewLocationFormatArr[2] = "~/Views/Shared/{1}/{0}.vbhtml";
        viewLocationFormatArr[3] = "~/Views/Shared/{1}/{0}.vbhtml";
        this.ViewLocationFormats = viewLocationFormatArr;

        string[] masterLocationFormatArr = new string[4];
        masterLocationFormatArr[0] = "~/Views/root/{1}/{0}.cshtml";
        masterLocationFormatArr[1] = "~/Views/root/{1}/{0}.vbhtml";
        masterLocationFormatArr[2] = "~/Views/Shared/{1}/{0}.vbhtml";
        masterLocationFormatArr[3] = "~/Views/Shared/{1}/{0}.vbhtml";
        this.MasterLocationFormats = masterLocationFormatArr;

        string[] partialViewLocationFormatArr = new string[4];
        partialViewLocationFormatArr[0] = "~/Views/root/{1}/{0}.cshtml";
        partialViewLocationFormatArr[1] = "~/Views/root/{1}/{0}.vbhtml";
        partialViewLocationFormatArr[2] = "~/Views/Shared/{1}/{0}.vbhtml";
        partialViewLocationFormatArr[3] = "~/Views/Shared/{1}/{0}.vbhtml";
        this.ViewLocationFormats = partialViewLocationFormatArr;

    }
}

确保在Application_Start事件中注册此自定义视图引擎。

ViewEngines.Engines.Clear();
var ourViewEngine = new MyCustomViewEngine();
ViewEngines.Engines.Add(ourViewEngine);
