推荐答案
FlowLayoutPanel仅用于以动态方式对其子控件进行布局.这并不意味着它们会在FlowLayoutPanel中自动调整大小.我猜想FlowLayoutPanel会忽略其子控件的Anchor属性.
The FlowLayoutPanel is only meant to layout it's child controls in a dynamic way. This does not mean that they will automatically resize within the FlowLayoutPanel. I'm guessing that the FlowLayoutPanel ignores the Anchor properties of it's child controls.
要实现此效果，您需要在FlowLayoutPanel的SizeChanged事件上手动调整子控件的大小.
To achieve this effect you'll need to manually resize your child controls on the FlowLayoutPanel's SizeChanged event.
但是，在这一点上，您可能需要重新考虑FlowLayoutPanel是否确实是您要使用的对象.如果您一直希望按钮填充FlowLayoutPanel的宽度，则不妨将其粘贴在Panel中并使用锚点，或者将其设置为Dock属性.
At this point though, you may want to reconsider whether the FlowLayoutPanel is really what you want to be using. If you know that you always want a button to fill the width of the FlowLayoutPanel, you might as well stick it in a Panel and use the anchors, or set it's Dock property.
