使用一个枚举在C＃中的数组索引 [英] Using an enum as an array index in C#

问题描述

我想这样做无异于这个问题，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]);

不过，我宁愿有一些不可或缺的话，而不是写这个容易出错代码。是否有一个内置在C＃模块，仅仅做到这一点？

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

如果您枚举项的值是contigious，数组方法非常有效。然而，在任何情况下，你可以使用词典< D​​ayOfTheWeek，串方式> （这是少高性能，顺便说一下）

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).
