WinForm RadioButton、CheckBox、ComboBox控件的使用

参考

环境

软件/系统	版本	说明
Windows	windows 10 专业版 22H2 64 位操作系统, 基于 x64 的处理器
Microsoft Visual Studio	Community 2022 (64 位) - Current 版本 17.13.6
.NET Framework	4.8

注意

RadioButton 需要放入同一容器才可以实现分组唯一选择。
ComboBox 如果通过 DataSource 赋值 List 数据，并且 List 是自定义类泛型，那么这个类、类属性需要设置为 public，并且属性要设置 { get; set; } ，否则会报错 无法绑定到新的显示成员，参数名：newDisplayMember
获取一组控件的值可以通过 容器.Controls 进行遍历处理。
