C# Sort List by multiple conditions

Question

I need to sort some soccer standings. My problem is how to sort in the right order.

Sortorder:

• Points DESC
• Approximation match
• Goal difference DESC
• Goals scored DESC
• Goals against

Input: TeamName - Points - GoalsScored - GoalsAgainst

• Team 1 - 1 - 4 - 7
• Team 2 - 5 - 8 - 6
• Team 3 - 1 - 2 - 10
• Team 4 - 8 - 12 - 5
• Team 5 - 5 - 7 - 4

... Match #4 - Team 5 - Team 2 -- 1-2

Match #7 - Team 1 - Team 3 -- 3-3 ...

Output: TeamName - Points - GoalsScored - GoalsAgainst

• Team 4 - 8 - 12 - 5
• Team 2 - 5 - 8 - 6
• Team 5 - 5 - 7 - 4
• Team 1 - 1 - 4 - 7
• Team 3 - 1 - 2 - 10

Because Team 2 won over Team 5 they ends up at 2nd place.

Because Team 1 draw against Team 3, they ends up at 4. place, with a better goal difference.

public class Standing
{
    public Team Team { get; set; }
    public int? MatchesPlayed { get; set; }
    public int? GoalsScored { get; set; }
    public int? GoalsAgainst { get; set; }
    public int? Points { get; set; }
}

public class Match
{
    public int MatchID { get; set; }
    public DateTime? PlayTime { get; set; }
    public Team HomeTeam { get; set; }
    public Team AwayTeam { get; set; }
    public int? HomeScore { get; set; }
    public int? AwayScore { get; set; }
}

public class Pool
{
    public int PoolID { get; set; }
    public string PoolName { get; set; }
    public DateTime? StartTime { get; set; }
    public List<Team> Teams { get; set; }
    public List<Match> Matches { get; set; }
    public List<Standing> Standings { get; set; }
}

Answer 1

Can you use .NET 3.5? It's pretty straightforward to use the LINQ OrderBy and ThenBy extension methods for this.

Answer 2

I think you should check out the IComparable interface and consider implementing it over your object(s).
