消息传递使您的视图模型脱钩.这就像一条推文，您向空中发送一条消息，有人可以阅读它，也可以有人注册来收听. UI使用PropertyChanged来了解某些更改并重新绘制值.
Messaging decouples your view models. It's like a Tweet, you send out a message into the air and someone can read it or someone could register to listen for it. PropertyChanged is used by the UI to know that something changed and to redraw the values.
消息传递绝对是最佳选择. MVVM指示灯具有内置选项来广播消息.您可以使用mvvminpc代码段.
Messaging is definitely the best choice. MVVM light has a built in option to broadcast the message. You can use the mvvminpc code snippet.
令人惊讶的是，您的帖子没有得到尽快答复.也许这个答案对外面的人还是有用的.
It's surprising your post wasn't answered sooner. Maybe this answer will still be useful to someone out there.
