循环遍历C#enum的键和值

Question

鉴于C#enum:

public enum stuffEnum: int
{
    New = 0,
    Old = 1,
    Fresh = 2
}

如何以一种我可以在一个循环中复制键及其值的方式循环它？就像是:

foreach(var item in stuffEnum)
{
    NewObject thing = new NewObject{
       Name = item.Key,
       Number = item.Value
    }
}

因此,最终会得到3个对象,其Name属性设置为"New","Old"和"Fresh",Number属性设置为0,1和2.

我该怎么做呢？

Answer 1

Enum类具有您正在寻找的方法.

foreach(int i in Enum.GetValues(typeof(stuff)))
{
    String name = Enum.GetName(typeof(stuff), i);
    NewObject thing = new NewObject
    {
        Name = name,
        Number = i
    };
}

Answer 2

您可以使用LINQ(几乎总是如此):

List<NewObject> stuff = Enum.GetValues(typeof(stuffEnum)).Cast<stuffEnum>()
    .Select(s => new NewObject { Name = s.ToString(), Number = (int) s })
    .ToList();

Answer 3

foreach (var enumValue in Enum.GetValues(typeof(StuffEnum)))
{
    Console.WriteLine("Name: {0}, Value: {1}", enumValue, (int)enumValue);
}

结果是

Name: New, Value: 0
Name: Old, Value: 1
Name: Fresh, Value: 2
