Question

Given a set var battingContribution = IQueryable<Player, Runs> (Basically a list of players and their total batting score) and another set var bowlingContribution = IQueryable<Player, Runs>, how do I pick whose net contribution was the best such that the player whose batting score minus the bowling score results in the highest net total?

Answer 1

The following works only for Players that are in both Contributions (although I don’t know an IQueryable with two type params):

var BestPlayer = (from a in (from bt in battingContribution from bw in BowlingContribution where bt.Player == bw.Player select new { Player = bt.Player, Diff = bt.Runs - bw.Runs)) orderby a.Diff descending select a).First().Player;

EDIT – as per comment from OP for completeness:

var BestPlayer = (from a in (from bt in batRuns from bw in bowlRuns where bt.Player == bw.Player select new { Player = bt.Player, Diff = bt.Runs - bw.Runs}) orderby a.Diff descending select a).First();
