5.使用StackPanel面板进行简单布局

 <StackPanel>
        <Label Content="Label"/>
        <Button Content="Button"/>
        <Button Content="Button"/>
        <Button Content="Button"/>
        <Button Content="Button"/>
    </StackPanel>

<Border Margin="5" Background="AntiqueWhite">
        <StackPanel>
            <Label Content="Label"/>
            <Button Content="Button"/>
            <Button Content="Button"/>
            <Button Content="Button"/>
            <Button Content="Button"/>
        </StackPanel>
    </Border>
