Question

I have a 3D array

String[][,] cross = {new String[,]{{"1", "b", "b", "b"}, {"b", "c", "c", "c"}},new String[,]{{"2", "b", "b", "e"}, {"b", "c", "c", "d"}}}

How to iterate over this array.

I want to iterate like this

foreach(String[,] abc in cross) //abc must be the first/second 2D array
  foreach(string[] arr in abc) //arr must hold {"1", "b", "b", "b"} (say)
  {
  }

I tried this, but not working.

Answer 1

Given your jagged array of 2D arrays, you would perform classic iteration like the following

foreach (string[,] array in cross)
{
   for (int i = 0; i < array.GetLength(0); i++)
   {
       for (int j = 0; j < array.GetLength(1); j++)
       {
           string item = array[i, j];
           // do something with item
       }
   }
}
