Question

我正在使用一个名为MVCForum的项目，并在解决方案中创建了一个新项目，出于演示目的，我们称之为“ExternalApp”。

现在，我已将ExternalApp引用添加到MCVForum应用程序，并可以调用控制器：http://mysite[.]com/TestController

其中“TestController”是我的外部控制器。也就是说，控制器存在于ExternalApp中。

问题是当我尝试从TestController中的“Test”返回视图时，找不到视图。

The view 'Index' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Themes/Metro/Views/Test/Index.cshtml
~/Themes/Metro/Views/Extensions/Test/Index.cshtml
~/Views/Extensions/Test/Index.cshtml
~/Views/Test/Index.cshtml
~/Views/Test/Index.vbhtml
~/Views/Shared/Index.cshtml
~/Views/Shared/Index.vbhtml

应用程序似乎正在查看它自己的视图项目，而不是在ExternalApp / Views文件夹中。如何让我的外部应用程序呈现正确的视图？

您可以创建自定义视图引擎，但如您所述here，您需要进行多项修改：

为了使MVCExternalApp项目中的视图在运行时可用，必须将它们复制到MVCForum输出文件夹中。除非您希望手动执行此操作，否则必须明确指出每个视图都要复制到输出。此选项强制文件进入bin文件夹。对于每个视图，右键单击并选择属性。更改“复制到输出目录”＆＃39;选项＆＃39;始终复制＆＃39;。这将确保在构建引用项目时始终将文件放入输出中。您还需要为Web.config执行此操作。

创建自定义视图引擎：

public class CustomViewEngine: RazorViewEngine 
{
   public CMSViewEngine()
   {               
       ViewLocationFormats = new string[] 
       {
           "~/Views/{1}/{0}.cshtml",
           "~/Views/{1}/{0}.vbhtml",
           "~/Views/Shared/{0}.cshtml",
           "~/Views/Shared/{0}.vbhtml",
           "~/bin/Views/{1}/{0}.cshtml", 
           "~/bin/Views/{1}/{0}.vbhtml", 
           "~/bin/Views/Shared/{0}.cshtml", 
           "~/bin/Views/Shared/{0}.vbhtml"
       };

       PartialViewLocationFormats = new[]
       {
           "~/Views/{1}/{0}.cshtml",
           "~/Views/{1}/{0}.vbhtml",
           "~/Views/Shared/{0}.cshtml",
           "~/Views/Shared/{0}.vbhtml",
           "~/bin/Views/{1}/{0}.cshtml", 
           "~/bin/Views/{1}/{0}.vbhtml", 
           "~/bin/Views/Shared/{0}.cshtml", 
           "~/bin/Views/Shared/{0}.vbhtml"
       };
   }
}

我只覆盖了PartialViewLocationFormats和ViewLocationFormats，但如果需要，你可以覆盖其余的位置;

在Global.asax中的Application_Start方法中注册视图引擎：

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);

    //Remove all view engine
    ViewEngines.Engines.Clear();

    //Add Custom view Engine Derived from Razor
    ViewEngines.Engines.Add(new CustomViewEngine());
}

您可以使用Razor Generator之类的内容将您的视图编译到ExternalApp程序集中，也可以在一个站点下单独运行这两个应用程序。
