Answer 1

 int[] data = {1,2,3,4,5,6,7,8,9};
int[][] result = Enumerable.Range(0, data.Count() / 3).Select(x => data.Skip(x*3).Take(3).ToArray()).ToArray();

Answer 2

 int[] x = {1,2,3,4,5,6,7,8,9};
int[][] result = Enumerable.Range(0, x.Count() / 3).Select(x => x.Skip(x*3).Take(3).ToArray()).ToArray();
