WPF Command 和 Event 有什么区别?
What is the difference between WPF Command and Event?
推荐答案
一般来说，您可以对事件执行几乎与使用命令相同的操作，只是处理用户交互的模式不同.
Generally speaking you can do almost the same with events as with commands, it is just a different pattern of handling user interaction.
Commands 允许您将命令处理程序的实现移动到业务层.命令结合了启用状态和执行，因此一切就绪.通过搜索 MVVM 模式了解更多信息.
Commands in WPF allow you to move the implementation of a command handler to the buisness layer. Commands combine Enable state and executation, so everything is in place. Reade more by searching for the MVVM pattern.
一开始，命令实现起来比较复杂，所以如果您的应用程序很小，您应该考虑只使用事件.
Commands are more complex to implement at first, so if your application is small you should consider just sticking to events.
