Difference between Lookup() and Dictionary(Of list())
I'm trying to wrap my head around which data structures are the most efficient and when / where to use which ones.
Now, it could be that I simply just don't understand the structures well enough, but how is an ILookup(of key, ...) different from a Dictionary(of key, list(of ...))?
Also where would I want to use an ILookup and where would it be more efficient in terms of program speed / memory / data accessing, etc?
