问题描述

根据此问题，并且最好使用此答案以及答案获取枚举属性，如何将枚举转换为一个字典，其中 Key 是枚举值本身和值是描述属性？

Based on this question, and preferably using this answer along with this answer to get enum attributes, how is it possible to cast the enum to a dictionary where Key is the enum value itself and Value is the description attribute?

推荐答案

给定 GetAttributeOfType& T>（）扩展方法你可以简单地做：

Given the GetAttributeOfType<T>() extension method you can simply do:

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

如果您直接要求描述的值：

If you directly want the Description in the value:

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