能否重新配置 MVC 路由解析机制？

Question

我已经实现了自定义 VirtualPathProvider 以从数据库中提供可自定义的视图，当我在 FileExists 方法上放置一个断点时，我注意到该框架执行了大量不必要的（对于我的项目）请求。例如，当我请求不存在的操作（例如http://localhost/Example/Action）时，框架会查找：

• "~/Example/Action/5"
• “~/Example/Action/5.cshtml”
• “~/Example/Action/5.vbhtml”
• “~/Example/Action.cshtml”
• “~/Example/Action.vbhtml”
• “~/Example.cshtml”
• “~/Example.vbhtml”
• “~/Example/Action/5/default.cshtml”
• “~/Example/Action/5/default.vbhtml”
• “~/Example/Action/5/index.cshtml”
• “~/Example/Action/5/index.vbhtml”
• “~/favicon.ico”
• “~/favicon.ico.cshtml”
• “~/favicon.ico.vb​​html”
• “~/favicon.ico/default.cshtml”
• “~/favicon.ico/default.vbhtml”
• “~/favicon.ico/index.cshtml”
• “~/favicon.ico/index.vbhtml”

当我发出与添加的路由匹配的请求（例如 http://localhost/Test）时，框架会查找：

• “~/测试”
• “~/Test.cshtml”
• “~/Test.vbhtml”
• “~/Test/default.cshtml”
• “~/Test/default.vbhtml”
• “~/Test/index.cshtml”
• “~/Test/index.vbhtml”

甚至在初始化控制器之前。初始化控制器后，框架会查找我已实现的自定义 RazorViewEngine 中定义的视图。

这是我的视图引擎

        AreaViewLocationFormats = new string[] { };
        AreaMasterLocationFormats = new string[] { };
        AreaPartialViewLocationFormats = new string[] { };
        MasterLocationFormats = new string[] { }; 
        ViewLocationFormats = new string[] { 
            "~/Views/Dynamic/{1}/{0}.cshtml",
            "~/Views/Dynamic/Shared/{0}.cshtml",
            "~/Views/{1}/{0}.cshtml",
            "~/Views/Shared/{0}.cshtml"
        };
        PartialViewLocationFormats = new string[] { 
            "~/Views/Dynamic/{1}/Partial/{0}.cshtml",
            "~/Views/Dynamic/Shared/Partial/{0}.cshtml",
            "~/Views/{1}/Partial/{0}.cshtml",
            "~/Views/Shared/Partial/{0}.cshtml"
        };
        FileExtensions = new string[] { "cshtml" };

那么问题是这些默认路由是否可以删除以及如何删除？

它们可能与RouteCollection.RouteExistingFiles 属性有关吗？我检查大量文件而不是只检查一个匹配的文件是没有意义的，但可能值得关闭它以查看它是否有任何区别。
