2021-11-22 WinFrom面试题 ComboBox控件绑定枚举类型如何实现？

Posted 2021-12-19 微软MVP Eleven

比如定义一个星期的枚举类型

public enum Weekdays

​

​ 星期一,星期二,星期三,星期四,星期五,星期六,星期日

​

​ //定义WeekDayInfo实体类

​ public class WeekDayInfo

public int DayValueget;set;

public string DayNameget;set;

​ //将枚举类型中的值转换成List

​ public List GetWeekDayList()

List list=new List();

foreach(int wdVal in Enum.GetValues(typeof(Weekdays)))

​ WeekDayInfo wd=new WeekDayInfo();

​ wd.DayValue=wdVal;

​ wd.DayName=Enum.GetName(typeof(Weekdays),wdVal);

​ list.Add(wd);

return list;

然后在Form1的Load事件中绑定数据源：

​ comboBox1.DisplayMember = “DayName”;

​ comboBox1.ValueMember = “DayValue”;

comboBox1.DataSource = GetWeekDayList();
