如何将具有描述属性的枚举转换为字典？

Question

基于此 question, and preferably using this answer along with this answer to get enum attributes，如何将枚举转换为字典，其中 Key 是枚举值本身，Value 是描述属性？

Answer 1

鉴于 GetAttributeOfType<T>() 扩展方法，您可以简单地执行以下操作：

var dic = Enum.GetValues(typeof(SomeEnum))
.Cast<SomeEnum>()
.ToDictionary(k => k, v => v.GetAttributeOfType<DescriptionAttribute>())

如果直接想要值中的Description：

var dic = Enum.GetValues(typeof(SomeEnum))
.Cast<SomeEnum>()
.ToDictionary(k => k, v => v.GetAttributeOfType<DescriptionAttribute>().Description)
