Whats the easiest/ most canonical way to convert from a multidimensional array into an array of arrays and vice versa?

For example, what is an elegant way to convert the following array of arrays int[][]

int[][] arrayArray = new int[][] {
    new int[] { 1, 2 },
    new int[] { 3, 4 },
    new int[] { 5, 6 },
    new int[] { 7, 8 }
};

Into an multidimensional int[,] which looks like:

int[,] array2D = new int[,] { 
    { 1, 2 }, 
    { 3, 4 }, 
    { 5, 6 }, 
    { 7, 8 }
};

Thanks!

@Keith and the other way? – ProgrammingLlama Dec 19 '18 at 02:03

Since the data is stored in memory differently for each, there is no super efficient approach, it just comes down to loops or if you want to get fancy linq – TheGeneral Dec 19 '18 at 02:05

I'm very surprised to see that this operation isn't as easy as one or two lines. Even when we assume that the data is a square matrix is it still as complicated? – flakes Dec 19 '18 at 02:08
