我加载了 4 个单选按钮，当我运行程序并单击它们时，如果我单击一个，然后单击另一个，其他按钮就会消失。如果我想有两个单选按钮但它们做不同的事情怎么办？
最佳答案
将不同的选择集分组到单独的组框(或面板，或其他容器控件，但组框可能是您想要的)。
MSDN :
Windows Forms RadioButton controls are designed to give users a choice among two or more settings, of which only one can be assigned to a procedure or object. For example, a group of RadioButton controls may display a choice of package carriers for an order, but only one of the carriers will be used. Therefore only one RadioButton at a time can be selected, even if it is a part of a functional group.
You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form.
假设您的表单上有四个或更多单选按钮。例如，如果您只有两个，并且您希望允许用户同时选择两个，请使用一组复选框。
