Question

我有一个MVC 5项目，包含许多控制器，模型和页面。为了使它们更易于维护，我将一些相关文件移动到一个名为Mail的新区域。

项目结构如下：

Automation (project's name)
 |- Controllers
 |- Views
 |- Models
 └── Areas  
      └── Mail
          └── Models 
          └── Controllers
               └── MailboxController
          └── Views
               └── Inbox.cshtml

我执行了以下步骤，以便能够加载新移动的视图：

更改区域中控制器的命名空间 - ＆gt;邮件 - ＆gt;控制器

将Rout添加到MailAreaRegistaration.cs，如下所示：

public override void RegisterArea(AreaRegistrationContext context)
{
    context.MapRoute(
        "Mail_default",
        "Mail/{controller}/{action}/{id}",
        new { action = "Inbox", id = UrlParameter.Optional},
        new [] { "Automation.Areas.Mail.Controllers" });
}

global.asax.cs中的RegisterAllAreaas（）

在项目的RoutConfig文件中更改MapRout方法，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 = "Dashboards", action = "Dashboard_Main", id = UrlParameter.Optional },
        namespaces: new [] {"Automation.Controllers"}
    );
}

主View文件夹中的所有页面都按预期呈现，但是当我想在Mail区域中加载inbox.cshtml时，会显示以下错误：

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

我测试了收件箱页面的下方网址，但没有人成功

我该如何解决？感谢

假设你有MailboxController这样的课程：

public class MailboxController : Controller
{
    // default action in area
    public ActionResult Inbox()
    {
        return View();
    }
}

首先，创建自定义类以在以下示例给出的区域文件夹中执行视图搜索：

namespace Automation
{    
    public class CustomRazorEngine : RazorViewEngine
    {
        public CustomRazorEngine()
        {
            // short note:
            // {2} = area name
            // {1} = controller name
            // {0} = action name
            AreaViewLocationFormats = new[]
            {
                // add these routes in area scope
                "~/Areas/{2}/Views/{0}.cshtml",
                "~/Areas/{2}/Views/{1}/{0}.cshtml",
            };

            ViewLocationFormats = new[]
            {
                // example routes
                "~/{1}/{0}.cshtml",
                "~/Views/{1}/{0}.cshtml"
            }

            FileExtensions = new[]
            {
                "cshtml"
            };
        }
    }
}

然后我在Global.asax中的Application_Start方法中注册自定义视图引擎：

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    ViewEngines.Engines.Add(new CustomRazorEngine()); // customized view search engine
    // other settings here
}

使用以上设置，以下网址应该有效：

http://localhost:port/Mail/Mailbox
http://localhost:port/Mail/Mailbox/Inbox

解决此问题的最简单方法是遵循MVC约定并将Inbox.cshtml文件移动到MVC所期望的Areas\Mail\Views\Mailbox\Inbox.cshtml位置（您只缺少Mailbox文件夹）。

但是，如果您打算根据自己的想法自定义视图位置，请使用Tetsuya's solution。
