Convert Multidimensional Array into Single Array

Convert multidimensional array into single array

Assuming this array may or may not be redundantly nested and you're unsure of how deep it goes, this should flatten it for you:

function array_flatten($array) { 
  if (!is_array($array)) { 
    return FALSE; 
  } 
  $result = array(); 
  foreach ($array as $key => $value) { 
    if (is_array($value)) { 
      $result = array_merge($result, array_flatten($value)); 
    } 
    else { 
      $result[$key] = $value; 
    } 
  } 
  return $result; 
}

Convert multidimensional array to list of single array

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();
