2 个解决方案

#1

You could use a Dictionary<Colour, int>:

你可以使用Dictionary : ,int>

Dictionary<Colour, int> dict = new Dictionary<Colour, int>();
dict[Colour.Red] = 230;
dict[Colour.Yellow] = 500;
dict[Colour.Green] = 50;
Console.WriteLine(dict[Colour.Red]) //outputs 230

The best solution is to use a dictionary:

最好的解决方案是使用字典:

var dictionary = new Dictionary<Colour, int>()

dictionary[Colour.Red] = 230;
dictionary[Colour.Yellow] = 500;
dictionary[Colour.Green] = 50;

Doing this, every colour exists at maximum once in the collection. If you're using a Collection or an Array, you'll be able to have multiple times the same colour in the collection.

这样做,每个颜色在集合中最多存在一次。如果您使用的是Collection或Array,则可以在集合中多次使用相同的颜色。
