How can I change the border thickness of a Groupbox on a windows form in C#?
提问by asdasdad
I didn't find any solution that helped me on the older questions on SO... Is it possible to make them thicker or just more visible by changing the color? If yes, some code would be great... or just a hint how to do it...

You'll need to make a custom GroupBoxcontrol. See The Grouper - A Custom Groupbox Control
您需要制作一个自定义控件GroupBox。请参阅Grouper - 自定义 Groupbox 控件

GroupBox is a custom drawn .Net control. You will need to hook into the Paint event, or derive from the GroupBox and override the OnPaint method, determine where the existing lines are being drawn and then draw overtop of them with wider lines to achieve the thicker border. Or you can create a custom control and paint everything yourself.
GroupBox 是一个自定义绘制的 .Net 控件。您需要挂钩 Paint 事件，或从 GroupBox 派生并覆盖 OnPaint 方法，确定绘制现有线条的位置，然后用更宽的线条在它们上面绘制以获得更粗的边框。或者您可以创建自定义控件并自己绘制所有内容。
