20141021--Two-dimensional arrays

Two-dimensional arrays::

int[,] ss = new int[3, 5] {{0, 1, 2, 3, 4}, {5, 6, 7, 8, 9}, {10, 11, 12, 13, 14}};

A two-dimensional array, Int[x,y] represents an X array, each containing Y elements

Value, Ss[m,n] represents the nth element of the number of arrays of M. The M,n index starts at 0.

The Foreach loop is only for array loops.
