推荐答案

I've a blog where I want to display the list of the latest posts, latest comments, post categories in a single view. How I can do that? I can strongly type my view to any one of the model right? There comes view model.

我创建 BlogViewModel 称为视图模型，包含最新的帖子，最新的评论和其他的东西，属性和我结合我的这个模型视图。在帖子，注释 ..是的域模型的，而 BlogViewModel 是的视图模型的我创建了专为视图。

I created a view model called BlogViewModel that contains latest posts, latest comments and other stuff as properties and I bind my view with this model. The posts, comments.. are domain models while the BlogViewModel is the view model I created specially for the view.

明天我会告诉我的博客在移动版本，在那个时候我可能会创建一个只包含较少的一个简单视图模型。最后..查看模型是观点和大多数时候，他们充当了真正的域模型包装！

Tomorrow I'll show my blog in a mobile version and at that time I may create a simple view model that contains only less properties. Finally.. view models are for views and most of the times they acts as wrappers over the real domain models!
