2. Second
3. Third
Solutions:
 

?

var list = new List<string>{         "First","Second","third"       };       var query = (from s in list                    select s)         .Select((obj, index) => index + ". " + obj);         foreach (string s in query)         Console.WriteLine(s);

2.

?

static void Main(string[] args)         {             string[] nums = {"One","Two", "Three"};               int X = 0;             var q = (from a in nums select new {ID = IncrementX(ref X), num = a});               foreach (var a in q)             {                 Console.WriteLine (a.ID.ToString() + ", " + a.num);             }             Console.ReadLine();         }           static int IncrementX(ref int X)         {             X+=1;             return X;         }

Example:

?

var query = from s in entities.Scores                     where s.Game.Id == guid                     orderby s.PlayerScore descending                     select new                     {                         PlayerName = s.PlayerName,                         PlayerScore = s.PlayerScore                     };           var list =  query.AsEnumerable()                     .Select((player, index) => new ScoreWithRank()                             {                                 PlayerName = player.PlayerName,                                 PlayerScore = player.PlayerScore,                                 Rank = index + 1;                             }                     .ToList(); listBox.ItemsSource = list.Select((player, index) => new                             {                                 PlayerName = player.PlayerName,                                 PlayerScore = player.PlayerScore,                                 Rank = index+=1                             }).ToList();
