如何创建包含 canvas 的弹出窗口 window？

Question

我正在创建一个小绘图程序，我希望在单击按钮时弹出 canvas。

private void buttonNewDrawing_Click(object sender, RoutedEventArgs e)
{
    MessageBox.Show(mainCanvas);
}

显然不起作用，因为它要求的是字符串。但是我可以使用什么来代替 MessageBox 来弹出 canvas mainCanvas 以便我可以使用它？

提前致谢。

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Button Click="Button_Click" Grid.Row="2" HorizontalAlignment="Center" HorizontalContentAlignment="Center" VerticalAlignment="Bottom" VerticalContentAlignment="Center" Content="Click"/>
    </Grid>
</Window>

MainWindow.xaml.cs:

private void Button_Click(object sender, RoutedEventArgs e)
{
    Window1 window = new Window1();
    window.Show();
}

    </Grid>
</Window>
