c# - 在 Unity3D 中写入嵌套字典

Question

我不能直接将值写入我的嵌套字典吗？

如果我能像这样访问它就好了:

public Dictionary<string, Dictionary<string, Dictionary<string, int>>> planets = 
   new Dictionary<string, Dictionary<string, Dictionary<string, int>>>();

planets[Planet.CharacterId]["MetalMine"]["Level"] = 0;

但是我得到:

KeyNotFoundException: The given key was not present in the dictionary.

这是否意味着我必须一个接一个地插入我的 Keys？

Answer 1

Does this mean I got to insert my Keys after each other?

是的，您需要按顺序初始化每个:

planets[Planet.CharacterId] = new Dictionary<string, Dictionary<string, int>>();
planets[Planet.CharacterId]["MetalMine"] = new Dictionary<string, int>();
planets[Planet.CharacterId]["MetalMine"]["Level"] = 0;

您可以在此处使用集合初始化器语法，但这不会使内容更具可读性和可维护性。

你似乎最好使用一个类而不是字典的字典:

public class Planet
{
    public List<Mine> Mines { get; set; }
}

public class Mine
{
    public string Type { get; set; }
    public int Level { get; set; }
}

var planets = new Dictionary<string, Planet>();

planets[Planet.CharacterId] = new Planet
{
    Mines = new List<Mine>
    {
        new Mine
        {
            Type = "Metal",
            Level = 0
        }
    };
}
