supporting for each loop in classes

how can i add "for each" 开发者_开发问答support for my class in c++0x and visual studio 2010?

I think the best way would be to add iterator support, with begin() and end() functions. The ranged-based for-loop uses them, and this also gives your class the richer set of functionality iterators provide.

You must make the class support the IEnumerable Interface
