use of tuples in C# 4.0

Question

Can i replace the following with a tuple and a list. Will there be any dip in performance or what is the best alternative.

1. Dictionary<string, Dictionary<string, User>>

Can I change this to the following

2. Dictionary<string, Tuple<string, Address>> userdata

Kindly suggest. Note: There seems to be no way to group tuples, so i think that 2 may be better be replaced by 1.

Of course you can group tuples if they are in a List - use LINQ. — slugster

Tuple will hold exactly one pair of values. Dictionary will hold an arbitraty number of such pairs. So of course 1 and 2 are not equivalent - one holds a collection of collections of pairs, another just a collection of pairs.

slugster is correct: you can group a list of tuples using linq GroupBy method.
