Cartesian Product + N x M Dynamic Array

Question

I have looked hours for a solution without any success. Hopefully someone can help me out.

I have a dynamic array of N items on M origin zip codes.

What you're looking to do is generate combinations of each item in the array.

Here's an example hard-coded for N == 3:

        var array1 = new[] { 1101, 5410, 60621 };
        var array2 = new[] { 1101, 60621 };
        var array3 = new[] { 60621 };

        foreach (var a in array1)
        {
            foreach (var b in array2)
            {
                foreach (var c in array3)
                {
                    Console.WriteLine("{0},{1},{2}", a, b, c);
                }
            }
        }

See if you can adapt that for N cases.
