convert a line of python code list comprehension / cross product (create a poker deck as a list of two characters strings: rank, suite) to C#

poker_deck = [r+s for r in '23456789TJQKA' for s in 'SHDC']

       

char[] figures = "23456789TJQKA".ToCharArray();

char[] suites = "SHDC".ToCharArray();

List<string> deck = new List<string>();

 

foreach (var figure in figures)

{

    foreach (var suite in suites)

    {

        deck.Add(string.Format("{0}{1}", figure, suite));

    }

}

       

var cards = from r in "23456789TJQKA"

            from s in "SHDC"

            select "" + r + s;

       

var cards = from r in "23456789TJQKA" from s in "SHDC" select "" + r + s;

       

var deck = "23456789TJQKA".SelectMany(

               figure => "SHDC".Select(

                   suite => string.Format("{0}{1}", figure, suite))).ToList();

       

public static IEnumerable<TOut> Pair<T1, T2, TOut>(this IEnumerable<T1> items1, IEnumerable<T2> items2, Func<T1, T2, TOut> pairer)

{

    return items1.SelectMany(item1 => items2.Select(item2 => pairer(item1, item2)));

}

       

var deck = "23456789TJQKA".Pair("SHDC", (figure, suite) => string.Format("{0}{1}", figure, suite));
