如何使用IPortable接口？

DNN编译出错：

De ion: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS0535: 'YourCompany.Modules.rollweb.rollwebController' does not implement interface member 'DotNetNuke.Entities.Modules.IPortable.ImportModule(int, string, string, int)'

Source Error:

出现这个报错是因为没有理解implement的概念，implement是面向对象里面的多重继承，你implement了一个接口，同时你还要实现这个接口的虚函数。

这个网页详细讲解了IPortable接口的使用。

对于报错，你用Google搜索“does not implement interface member  ”就会找到微软的文档：
