如何从 ASP.NET MVC3 应用程序提供 favicon.ico 和 robots.txt 文件

Question

ASP.NET MVC3 应用程序作为虚拟主机托管在 Mono 中的 Apache 中，地址为 http://www.mysite.com

对文件 robots.txt 、 favicon.ico 和 apple-touch-icon.png 的请求导致以下 404 错误，因为 这些名称没有 MVC3 控制器。 如何提供这些文件？是否可以强制 Apache 将它们作为常规文件提供服务，或者我们可以强制 MVC3 应用程序返回这些文件？ 哪种方法是正确的实现方式？

System.Web.HttpException: The controller for path '/robots.txt' was not found or does not implement IController.

右击项目名称，选择“添加->新建项目”
选择“文本文件”并将其命名为“robots.txt”
您可以将此文件留空

修复 favicon.ico：

转到 Global.asax.cs 文件的 RegisterRoutes 方法并将其添加到顶部附近：您可以查看此页面以获取更多信息：Favicon Icon-MVC3 ASP.NET
