Linq - Top value from each group

Question

How can I employ Linq to select Top value from each group

when I have a code segment like :

var teams = new Team[]
 { 
  new Team{PlayerName=\"Ricky\         


        

Answer 1

I would suggest you first implement an extension method on the IEnumerbale class called Top For example:

IEnumerable Top(this IEnumerable target, Func keySelector, int topCount)
{
    return target.OrderBy(i => keySelector(i)).Take(topCount);
}

Then you can write:

teams.GroupBy(team => team.TeamName).Top(team => team.PlayerScore, 1).

There might be some slight modifications to make it compile.
