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

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 DayValue{get;set;}

public string DayName{get;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();
