c# - 根据索引检索枚举的值 - C#

Question

这是我的枚举:

public enum DocumentTypes
    {
        [EnumMember]
        TYPE_1 = 1,
        [EnumMember]
        TYPE_2 = 2,
        [EnumMember]
        TYPE_3 = 3,
        [EnumMember]
        TYPE_4 = 4,
        [EnumMember]
        TYPE_5 = 5,
        [EnumMember]
        TYPE_6 = 6,
        [EnumMember]
        TYPE_7 = 7,
        [EnumMember]
        TYPE_8 = 12

    }

如果我想获取'TYPE_8'，如果我只有12个，有没有办法获取枚举值？

我试过这个:

((DocumentTypes[])(Enum.GetValues(typeof(DocumentTypes))))[Convert.ToInt32("3")].ToString()

返回值“TYPE_4”

Answer 1

可以直接投:

int value = 12;
DocumentTypes dt = (DocumentTypes)value;
