i have tow queries one is

  List<int> Scores = new List<int>() { 97, 92, 81, 60 };
IEnumerable<int> queryHighScores =
            from a in Scores
            where a < 5
            select a;

and the other is

       int[] numbers = { 12, 43, 44, 323, 44, 45, 34 };
        var query1 = from a in numbers
                     where a < 5 
                     select a;

now anybody tell me what is IEnumerable and why we use this . both query return same result so why we use IEnumerable

it has something to do with indexers – Arun Prasad E S Jun 02 '16 at 09:46
both queries return an `IEnumerable`. If you _declare_ your variable with `var` or `IEnumerable` is a matter of taste. Don't understand the question... – René Vogt Jun 02 '16 at 09:50

why we cannot add more numbers in second query? – SUPER_USER Jun 02 '16 at 09:59
