使用LINQ：

using System.Linq;

var ranked = playerScores.Select((score, index) => 
                                 new {Player=index+1, Score=score})
                         .OrderByDescending(pair => pair.Score)
                         .ToList();

然后显示获胜者，例如：

And then display the winner, for example:

Console.WriteLine(String.Format("Winner: Player {0} with score {1}", 
                  ranked[0].Player, ranked[0].Score));
