How to take all but the last element in a sequence using LINQ?

Question

Let\'s say I have a sequence.

IEnumerable sequence = GetSequenceFromExpensiveSource();
// sequence now contains: 0,1,2,3,...,999999,1000000
         


        

Answer 1

I would probably do something like this:

sequence.Where(x => x != sequence.LastOrDefault())

This is one iteration with a check that it isn't the last one for each time though.
