双射词典/地图在C＃
是否有有效的存储键/值对，其中键和值是不同的，因此，双射映射（即TryGetValue / TryGetKey）是可能的双射字典in.NET？天真的方法是有两个内置的字典：一个键值和值密钥字典，但这不是有效的在内存方面
Is there a bijective dictionary in.NET that efficiently stores Key/Values pairs, where both keys and values are distinct, so a bijective mapping (i.e. TryGetValue/TryGetKey) is possible? The naive approach would be to have two internal dictionaries: A key-value and a value-key dictionary, but this is not efficient in terms of memory.
我不相信有一在.NET。根据不同的键/值类型，我不知道该使用两个字典有可能造成的是的多大的效率损失：这是我会做什么，直到我看到了问题的基础上，事实上，它是简单的。
I don't believe there's one in .NET. Depending on the key/value types, I'm not sure that using two dictionaries is likely to cause that much of an efficiency loss: it's what I'd do until I saw a problem, based on the fact that it's simple.
在事实上，它的非常的简单，因为我已经在另一个堆栈溢出的答案付诸实施。我去看看我能找到它...
In fact, it's very simple as I've already implemented it in another Stack Overflow answer. I'll see if I can find it...
编辑：我发现了两个：
- One of mine
- Another based on mine, but more fully developed with Remove etc.
