为什么 Enum.GetValues 比迭代更好？
Why is Enum.GetValues better than iterating?
我正在阅读this答案
By the way, incrementing the value is not a good way to enumerate the
values of an enum. You should do this instead.
I would use Enum.GetValues(typeof(Suit)) instead.
为什么？ GetValues 比迭代有何优势？
看来你误解了那里的上下文。
您所指的答案的海报建议使用 GetNames 遍历枚举的 names。但是他说，当谈到 值 时，枚举超过 GetValues 比递增更好。
所以一个并不比另一个好，它们很好地服务于不同的目的，答案的作者概述了这一点。
正如@knittl 所述：
Because you can have "holes" in your enum. Consider enum E { A = 1, B =
2, C = 4 }. Incrementing will yield A, B, 3, C enumerating over all
values will yield A, B, C
感谢@Andrei 指出：
enum might be defined with any values. Even with chars. So
incrementing might give you a lot of stuff that is no in the enum.
GetValues is guaranteed to return only relevant values though
