在ASP.NET 2.0中可以同是调用VB,C#中的类.
By default, the App_Code directory can only contain files of the same language. However, you may partition the App_Code directory into subdirectories (each containing files of the same language) in order to contain multiple languages under the App_Code directory. To do this, you need to register each subdirectory in the Web.config file for the application. 可以在WEB.CONFIG中申明一个用于放置其他语言的子目录.
web.config
