WPF MVVM 项目实例 MVVM是Model-View-ViewModel的简写。它本质上就是MVC 的改进版。MVVM 就是将其中的View 的状态和行为抽象化，让我们将视图 UI 和业务逻辑分开。当然这些事 ViewModel 已经帮我们做了，它可以取出 Model 的数据同时帮忙处理 View 中由于需要展示内容而涉及的业务逻辑。(WPF MVVM project example MVVM is the shorthand for Model-View-ViewModel. It is essentially an improved version of MVC. MVVM abstracts the state and behavior of View, so that we can separate the view UI from the business logic. Of course, these things have been done by ViewModel, which can take out Model data and help handle the business logic involved in View as it needs to be displayed.)
