c# - How to use LINQ on a multidimensional array to 'unwind' the array?

Question

Consider the following array:

int[,] numbers = new int[3, 2] { { 2, 1 }, { 3, 4 }, { 6, 5 } };

I would like to use LINQ to construct an IEnumerable with numbers 2, 1, 3, 4, 6, 5.

What would be the best way to do so?

Answer 1

Perhaps simply:

var all = numbers.Cast<int>();
