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：
- “~/示例/动作/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.vbhtml”
- “~/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" };
所以问题是这些默认路由可以被删除吗？如何删除？
