C# 有些控件没有拉伸

在这个窗口中，我有许多不同的控件，我想拉伸，这是可能的 但是“stackGroup”、“listBox1”、“listBox2”中的一些控件没有拉伸。。为什么？ 也是这样我做这种页面对吗

与中的答案相同。StackPanel不会在与其方向相同的方向上进行拉伸对齐。因此，方向为垂直的StackPanel不会考虑子对象拉伸的垂直对齐

listBox1不拉伸，因为它的垂直对齐是拉伸的，并且它的容器StackPanel的方向是垂直的（这是它的默认方向）。您可以将StackPanel更改为水平，用另一个容器（例如DockPanel）替换它，或者完全删除它，因为它只包含一个元素

类似的推理也适用于您的其他问题

在哪个方向它们不会拉伸宽度或高度？stackGroup仅适用于左方向和右方向，但不适用于底部方向。listbox1和listbox2不向任何一个方向工作
