Grid——网格布局，其中控件或容器需指定位置
StackPanel——堆叠面板，其中的控件水平布局、竖直布局
DockPanel——停靠面板，内部控件或容器可以放置在上、下、左、右
WrapPanel——可以看作是具有自动换行功能的StackPanel容器。窗体太小时，其末尾的控件会自动换行。像Java中的流布局
布局原则：先整体规划（Grid），再局部规划（Grid、StackPanel等）
如下图，Grid有5行3列，具体布局、控件查看文档大纲

</Window>【GroupBox】GroupBox内只能有一个元素，可用StackPanel承载多个控件
布局、控件如图所示

<StackPanel DockPanel.Dock="Right" Width="30"/>
<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
<Label Content=" 中间地带，是我的天下" />
</StackPanel>
</DockPanel>
</Window>【WrapPanel】可以看作是具有自动换行功能的StackPanel容器。默认从左到右排列。
左图最后一个Button的高度会变成最小尺寸。Orientation="Vertical"得到右图（默认水平布局）
