在C＃中使用枚举作为数组索引 [英] Using an enum as an array index in C#

问题描述

我想要执行与此问题相同的操作，那就是：

I want to do the same as in this question, that is:

enum DaysOfTheWeek {Sunday=0, Monday, Tuesday...};
string[] message_array = new string[number_of_items_at_enum];

...

Console.Write(custom_array[(int)DaysOfTheWeek.Sunday]);

但是，我宁愿有一些内在的东西，而不是写这个错误的代码。在C＃中有一个内置的模块，只是这样吗？

however, I would rather have something integral to so, rather than write this error prone code. Is there a built in module in C# that does just this?

推荐答案

如果枚举项的值是连续的，方法工作得很好。但是，无论如何，您可以使用字典< DayOfTheWeek，字符串> （其性能较差）。

If the values of your enum items are contigious, the array method works pretty well. However, in any case, you could use Dictionary<DayOfTheWeek, string> (which is less performant, by the way).
