建立在
this question,是否有一个简单的解决方案,有一个多键字典,其中任何一个键可以用来识别价值？
即.
MultikeyDictionary<TKey1,TKey2,TValue> foo; foo.Add(key1,key2,value); myValue = foo[key1]; // value == myValue foo.Remove(key2); myValue = foo[key1]; // invalid,Exception or null returned
解决方法
This blog post似乎详细描述了一个相当体面的实现.
Multi-key generic dictionary class for C#
MultiKeyDictionary is a C# class that wraps and extends the Generic Dictionary object provided by Microsoft in .NET 2.0 and above. This allows a developer to create a generic dictionary of values and reference the value list through two keys instead of just the one provided by the Microsoft implementation of the Generic Dictionary<…>. You can see my article on CodeProject (here),however this code is more up-to-date and bug free.
