C# Ranking of objects, multiple criteria

Question

I am building a plugin for a LAN party website that I wrote that would allow the use of a Round Robin tournament.

All is going well, but I have some questions about

Answer 1

I realize I'm late to the party, but I wanted to take a shot anyhow.

Here is a version which uses LINQ exclusively:

private IEnumerable GetRankings(Dictionary wins, Dictionary scores)
{
    var overallRank = 1;

    return
        from team in wins.Keys
        group team by new { Wins = wins[team], TotalScore = scores[team] } into rankGroup
        orderby rankGroup.Key.Wins descending, rankGroup.Key.TotalScore descending
        let currentRank = overallRank++
        from team in rankGroup
        select new TeamRank(team, currentRank, rankGroup.Key.Wins, rankGroup.Key.TotalScore);
}

The return type:

public class TeamRank
{
    public TeamRank(TournamentTeam team, int rank, double wins, double totalScore)
    {
        this.Team = team;
        this.Rank = rank;
        this.Wins = wins;
        this.TotalScore = totalScore;
    }

    public TournamentTeam Team { get; private set; }

    public int Rank { get; private set; }

    public double Wins { get; private set; }

    public double TotalScore { get; private set; }
}
