推荐答案

您实施WPF应用程序的模型 - 视图 - 视图模型模式，或使用数据绑定呢？

Are you implementing the Model-View-ViewModel pattern in your WPF application, or using databinding at all?

您不必使用MVVM，但你确实应该以某种方式使用数据绑定。

You don't have to use MVVM, but you should really be using databinding in some fashion.

通过数据绑定，你该按钮的内容有些对象（视图模型在MVVM）的字符串属性绑定。该对象需要实现 INotifyPropertyChanged的接口。您可以绑定子窗口同一对象的相同属性的文本框。

With databinding, you'd bind the button content to a string property of some object (a view-model in MVVM). That object needs to implement the INotifyPropertyChanged interface. You can bind the textbox on the child window to the same property of the same object.

通过在地方，该按钮会自动更新，当用户在一个新的球员的名字。

With that in place, the button will be updated automatically when the user types in a new player name.
