推荐答案

您需要有一个要关闭的窗口实例，您可以在打开窗口时创建一个共享类，并放置一个引用对象到您的窗口，然后稍后将其关闭，

但您始终可以针对此问题找到更好的解决方案，

您需要更多地考虑如何组织您的应用，并使之清晰易懂.

you need to have an instance form the window that you want to close you can make a shared class when your window open put a reference object to your window then close it later,

but you always have a better solution for this problem,

you need to think more about how to organize your app and make it clear and ease to understand.
