Question

I have table Players with columns: ID Name Points

What is most efficient way to get player position ordered by points using LINQ?

Answer 1

Any solution will require at least one iteration through all elements, but the following will suffice:

var ordered = players.OrderByDescending(p => p.Points).ToList();

This will order the elements in one pass and then store the result in a list to preserve the ordering without need to ‘order’ again:

int position = ordered.IndexOf(player);
