在Win UI 3中，如何更改主窗口页面？

在Win UI 3中，当用户单击按钮时，我想更改MainWindow的内容。现在，我拥有所有内容的MainWindow，然后用户单击一个按钮，然后打开一个新窗口，我们将其称为SecondWindow。我这样做是：

Window secondWindow= new SecondWindow();
secondWindow.Activate();

但是我想要的是要在主窗口中打开Secondwindow的内容，代替MainWindow的内容。我该怎么做？

In Win UI 3 I want to change the content of the MainWindow when the user clicks a button. Right now I have the MainWindow with all its content, then the user clicks a button and a new window opens, let's call it SecondWindow. I do this with:

Window secondWindow= new SecondWindow();
secondWindow.Activate();

But what I want is for SecondWindow's content to open in the main window, in place of MainWindow's content. How can I do this?

如果您希望在另一个窗口内显示secondwindow的内容，则应是usercontrol而不是窗口。

然后，您可以简单地作为主窗口的根面板的孩子添加一个实例：

mainwindow.xaml：

<Window ...>
    <Grid x:Name="root">
...

mainwindow.xaml.cs：，

this.grid.Children.Clear();
this.grid.Children.Add(new YourUserControl());

如果您定义了内容直接在窗口中，您应该将其content添加到主窗口中：

Window secondWindow = new SecondWindow();
var root = secondWindow.Content;

this.grid.Children.Clear();
this.grid.Children.Add(root);

secondWindow.Close();

If you want the display the contents of the secondWindow inside another window, it should be a UserControl instead of a window.

You could then simply add an instance of it as a child of the root panel of the main window:

MainWindow.xaml:

<Window ...>
    <Grid x:Name="root">
...

MainWindow.xaml.cs:

this.grid.Children.Clear();
this.grid.Children.Add(new YourUserControl());

If you define the contents directly in a window, you should add its Content to the main window like this:

Window secondWindow = new SecondWindow();
var root = secondWindow.Content;

this.grid.Children.Clear();
this.grid.Children.Add(root);

secondWindow.Close();
