How do you need to access the keys? Do you actually need them sorted as
well?

Do you need to have sorted access to the values on a regular basis, or
just once occasionally? (You could sort when you needed them if it's
the latter.)

SortedList<stri ng, doublestudents;
string is their name
double is their GPA
student's name and his GPA are always together (KeyPair)

I need to get a list of names ranked by their GPAs


Just need to sort it once.
Thanks

In that case, given that SortedList<TKey ,TValueimplemen ts
IEnumerable<Key ValuePair<TKey, TValue>I'd just do something like:

grades.OrderBy( entry =entry.Value)

That will return an IEnumerable<Key ValuePair<strin g,double>which you
can then convert into a list (call ToList) or just iterate over with
foreach.

By the way, I'd stongly recommend using decimal instead of double for
a GPA.
