The scenario is for a football league table. I can order the list by match win percentage and then by goals scored to determine their position in the league. I then use this ordering to get teams position in the league table using the IndexOf
function.
this.results = this.results.OrderByDescending(x => x.WinPercentage).ThenByDescending(x => x.Goals);
this.results.Foreach(x => x.Position = this.results.IndexOf(x));
The problem arises when two teams (should be joint #1) have the same match win percentage and goals scored but when getting the index one team will be assigned #1 and the other #2.
Is there a way to get the correct position?
var position = 1;
var last = result.First();
foreach(var team in results)
{
if (team.WinPercentage != last.WinPercentage || team.Goals != last.Goals)
++position;
team.Position = position;
last = team;
}
