如何关闭窗口但仍使应用程序处于活动状态? [英] How to close a window but still have app current active?

问题描述

假设我有 2 个窗口:InputWindow 和 DisplayWindow

suppose i have 2 windows: InputWindow and DisplayWindow

当前:我想使用 InputWindow 通过 App 变量保存数据

Currently:i want to use InputWindow to hold data via an App variable

// in InputWindow
(App.Current as App).u_id = obj.id;

其中 u_id 是我在 app.xaml.cs 中定义的对象，obj.id 是 InputWindow 中的输入变量.

where u_id is the object i defined in app.xaml.cs and obj.id is the input variable in InputWindow.

但是，当我关闭 InputWindow 并显示 DisplayWindow 时:

However when i close InputWindow and display DisplayWindow:

// in InputWindow
DisplayWindow window = new DisplayWindow();
window.Show();
Application.Current.MainWindow.Close();

该应用程序还会杀死 InputWindow 中的数据.

The app also kill the data in the InputWindow.

所以我的问题是:

有没有办法将数据从关闭的窗口保存到打开的窗口?

Is there a way to keep the data via from the closed Window to the open Window?

推荐答案

        Application.Current.MainWindow.Hide();

您可以使用此行隐藏窗口...或者您可以使用构造函数将要使用的信息传递到新窗口中.

You can hide the window using this line... or you can pass the information that you want to use into the new window using the constructor.

        DisplayWindow window = new DisplayWindow(object myObject);

那个构造函数必须有你想要传递的信息，但这也可以解决问题.

That constructor must have the information you want passed but this can solve the issue as well.
