Question

There are several places on the internet that talk about having multy key dictionary such as in:

Multi-key dictionary in c#?

Or

Multi-key dictionaries (of another kind) in C#?

I am looking for a multi key dictionary that will enable me to retrieve the object that I am looking for as long as I provide just one key. In other words If I where to have:

 // multyKeyDictionary = instance of a multikeydictionary 
 multyKeyDictionary.add(key1, key2, someObject);

then I will like to be able to retrive someObject as:

multyKeyDictionary[key1]; or multyKeyDictionary[key2];

Answer 1

Well, I don’t understand why don’t you just use regular dictionary and add object twice with different keys.

Dictionary<string, object> dict = new Dictionary<string, object>();
dict.Add("key1", obj);
dict.Add("key2", obj);

// dict["key1"] == dict["key2"]
