List<Player> players = new List<Player>();

players.Add(new Player() { Id = "1", Name = "angle" });
players.Add(new Player() { Id = "2", Name = "cristin" });
players.Add(new Player() { Id = "2", Name = "robert" });

var finded= players.Where(x => x.Name == "cristin").FirstOrDefault();

public class Player
{
   public string Id { get; set; }
   public string Name { get; set; }
}

Answer 3

How about this:

public int GetIndex(List<PlayerClass> playersList, PlayerClass player)
{
    return playersList.FindIndex(a => a == player);
}

It should return -1 if the player is not in the list.
