Not really.  A dictionary is just a set of pairs, where equality is defined by 
comparing just the first elements of the pairs.  An array is an ordered 
collection where an elements can occur multiple times.  A set is an unordered 
collection where elements may occur at most once.  They have very little in 
common.
