枚举

// 枚举
public enum enumStudent
{
    [Description("性别")]
    sex = 0,
    [Description("年龄")]
    age = 1,
}
 
// 获取方法
public string GetDescriptionByEnum(Enum enumValue)

    string value = enumValue.ToString();
    System.Reflection.FieldInfo field = enumValue.GetType().GetField(value);

        return value;
    DescriptionAttribute descriptionAttribute = (DescriptionAttribute)objs[0];

// 调用示例
GetDescriptionByEnum(enumStudent.age) → 年龄
