如何在C#中枚举枚举?
例如,以下代码无法编译:
public enum Suit
{
Spades,
Hearts,
Clubs,
Diamonds
}
public void EnumerateAllSuitsDemoMethod()
{
foreach (Suit suit in Suit)
{
DoSomething(suit);
}
}
它给出了以下编译时错误:
“Suit”是“type”,但与“variable”类似
它在第二个Suit关键字上失败。
我使用ToString(),然后拆分并解析flags中的spit数组。
[Flags]
public enum ABC {
a = 1,
b = 2,
c = 4
};
public IEnumerable<ABC> Getselected (ABC flags)
{
var values = flags.ToString().Split(',');
var enums = values.Select(x => (ABC)Enum.Parse(typeof(ABC), x.Trim()));
return enums;
}
ABC temp= ABC.a | ABC.b;
var list = getSelected (temp);
foreach (var item in list)
{
Console.WriteLine(item.ToString() + " ID=" + (int)item);
}
我想这对你有帮助。
public class Program
{
public static List<T> GetEnamList<T>()
{
var enums = Enum.GetValues(typeof(T)).Cast<T>().Select(v => v).ToList();
return enums;
}
private void LoadEnumList()
{
List<DayofWeek> dayofweeks = GetEnamList<DayofWeek>();
foreach (var item in dayofweeks)
{
dayofweeks.Add(item);
}
}
}
public enum DayofWeek
{
Monday,
Tuesday,
Wensday,
Thursday,
Friday,
Sturday,
Sunday
}
