MultiDimensional 2D int array to string List
I would like to convert my array2D:
int[,] array2D = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };
to a List:
List<String> numbers = new List<string>(array2d.ToString());

You can flatten a multi-dimensional array with Enumerable.Cast
List<String> number = array2D.Cast<int>().Select(i => i.ToString()).ToList();

You can convert 2d array into jagged array and then convert it to List.
int[,] arr = new int[,] { { 1, 2, 3 }, { 4, 5, 6 } };
int[][] jagged = new int[arr.GetLength(0)][];
for (int i = 0; i < arr.GetLength(0); i++)
{
jagged[i] = new int[arr.GetLength(1)];
for (int j = 0; j < arr.GetLength(1); j++)
{
jagged[i][j] = arr[i, j];
}
}
List<int[]> list = jagged.ToList();
