How could I take 1 more item from Linq's TakeWhile?

Question

(line of code of interest is the last one, the rest is just for a full representation)

Using the following code, I wanted to take VOTERS until I exceeded

Answer 1

You're looking for

voters.TakeWhile(p => {
   bool exceeded = voicesSoFar > voicesNeeded ;
   voicesSoFar += p.Voices;
   return !exceeded;
});

If you insist on a one-liner, this will work by comparing the previous value:

voters.TakeWhile(p => (voicesSoFar += p.Voices) - p.Voices < voicesNeeded);
