在C＃多维重点哈希表 [英] Hashtable with MultiDimensional Key in C#

问题描述

我基本上寻找一种方式使用C＃中的二维输入的密钥来访问一个哈希表值。

最后，我将能够做这样的事

 哈希表[1] [虚假] = 5;
int类型的哈希表= [1] [虚假]
// 1 = 5
 

这是我一直在努力......没有奏效

  Hashtable的试验=新的Hashtable（）;
test.Add（新字典＆LT; INT，BOOL＆GT;（）{{1，真实}}，555）;
字典＆LT; INT，BOOL＆GT;临时=新词典＆LT; INT，BOOL＆GT;（）{{1，真实}};
字符串testz =试验[临时]的ToString（）;
 

解决方案

我认为更好的办法是封装的多维关键的许多领域成为一个类/结构。例如：

 结构键{
  公共只读INT DIMENSION1;
  公共只读布尔DIMENSION2;
  公钥（INT P1，P2布尔）{
    DIMENSION1 = P1;
    DIMENSION2 = P2;
  }
  // equals和GetHash code ommitted
}
 

现在，您可以创建并使用一个正常的哈希表，并使用此包装作为一个密钥。

I'm basically looking for a way to access a hashtable value using a two-dimensional typed key in c#.

Eventually I would be able to do something like this

HashTable[1][false] = 5;
int a = HashTable[1][false];
//a = 5

This is what I've been trying...hasn't worked

Hashtable test = new Hashtable();
test.Add(new Dictionary<int, bool>() { { 1, true } }, 555);
Dictionary<int, bool> temp = new Dictionary<int, bool>() {{1, true}};
string testz = test[temp].ToString();

解决方案

I think a better approach is to encapsulate the many fields of your multi-dimensional key into a class / struct. For example

struct Key {
  public readonly int Dimension1;
  public readonly bool Dimension2;
  public Key(int p1, bool p2) {
    Dimension1 = p1;
    Dimension2 = p2;
  }
  // Equals and GetHashCode ommitted
}

Now you can create and use a normal HashTable and use this wrapper as a Key.
