c#模拟未知键数的关联数组(类似于PHP)

是否有可能创建像PHP这样的关联数组?我不打算创造一款带有玩家数据的游戏,但我可以很容易地用这种方式解释我想要什么:
player["Name"] = "PName";
player["Custom"]["Gender"] = "Female";
player["Custom"]["Style"] = "S1";
player["Custom"]["Face"]["Main"] = "FM1";
player["Custom"]["Face"]["Eyes"] = "FE1";
player["Custom"]["Height"] = "180";
长度必须是动态的,我不知道将有多少个键:
player["key1"]["key2"]=value
player["key1"]["key2"]["key3"]["key4"]...=value
我需要的是这样的东西:
string name = player["Name"];
string gender = player["Custom"]["Gender"];
string style = player["Custom"]["Style"];
string faceMain = player["Custom"]["Face"]["Main"];
string faceEyes = player["Custom"]["Face"]["Eyes"];
string height = player["Custom"]["Height"];
或者以类似的方式
我一直在努力:
Dictionary<string, Hashtable> player = new Dictionary<string, Hashtable>();
player["custom"] = new Hashtable();
player["custom"]["Gender"] = "Female";
player["custom"]["Style"] = "S1";
但是问题从这里开始(只适用于2个键):
player["custom"]["Face"] = new Hashtable();
player["Custom"]["Face"]["Main"] = "FM1";
c#是强类型的,所以复制这种行为似乎不容易。
一个"可能性":
public class UglyThing<K,E>
{
private Dictionary<K, UglyThing<K, E>> dicdic = new Dictionary<K, UglyThing<K, E>>();
public UglyThing<K, E> this[K key]
{
get
{
if (!this.dicdic.ContainsKey(key)) { this.dicdic[key] = new UglyThing<K, E>(); }
return this.dicdic[key];
}
set
{
this.dicdic[key] = value;
}
}
public E Value { get; set; }
}
用法:
var x = new UglyThing<string, int>();
x["a"].Value = 1;
x["b"].Value = 11;
x["a"]["b"].Value = 2;
x["a"]["b"]["c1"].Value = 3;
x["a"]["b"]["c2"].Value = 4;
System.Diagnostics.Debug.WriteLine(x["a"].Value); // 1
System.Diagnostics.Debug.WriteLine(x["b"].Value); // 11
System.Diagnostics.Debug.WriteLine(x["a"]["b"].Value); // 2
System.Diagnostics.Debug.WriteLine(x["a"]["b"]["c1"].Value); // 3
System.Diagnostics.Debug.WriteLine(x["a"]["b"]["c2"].Value); // 4
