多維數組與字符串鍵

Question

如何在c＃中創建多維數組？

我想要分配這樣的價值觀：

myArr["level1"]["enemy"][0] = 1; 
myArr["level1"]["enemy"][1] = 4; 

myArr["level1"]["friend"][0] = 2; 
myArr["level1"]["friend"][1] = 3; 

我可以用

public Array level1; 

做正常的陣列和值壓到它。

但我似乎無法做到多維一個

我想你在C＃中有最similer事情是一個Dictionary：

Dictionary<Person, string> dictionary = new Dictionary<Person, string>(); 
Person myPerson = new Person(); 
dictionary[myPerson] = "Some String"; 
... 
string someString = dictionary[myPerson]; 
Console.WriteLine(someString); // "Some String" 

你可以把字典和builed某種元組結構作爲關鍵字：

public class TwoKeyDictionary<K1,K2,V> 
{ 
    private readonly Dictionary<Pair<K1,K2>, V> _dict; 

    public V this[K1 k1, K2 k2] 
    { 
     get { return _dict[new Pair(k1,k2)]; } 
    } 

    private struct Pair 
    { 
     public K1 First; 
     public K2 Second; 

     public override Int32 GetHashCode() 
     { 
      return First.GetHashCode()^Second.GetHashCode(); 
     } 

     // ... Equals, ctor, etc... 
    } 
}
