Here's a quick console app to illustrate the point in my previous post. Notice how much easier it is to pass a row of the jagged array to a method, compared to passing a row of a rectangular array: using System; class Test { static void Main() { // create rectangular array int[,] rect = {{1,2,3}, {4,5,6}, {7,8,9}}; // create jagged array int[][] jagged = new int[3][]{new[]{1,2,3}, new[]{4,5,6}, new[]{7,8,9}}; // print first row of rectangular array int[] row1 = new int[rect.GetLength(0)]; for(int i = 0; i PrintArray(row1); Console.WriteLine(); // print first row of jagged array PrintArray(jagged[0]); Console.ReadKey(); } static void PrintArray(int[] ia) { foreach(int i in ia) Console.WriteLine(i); } }

Even in cases were the array elements are all of the same length, it may be more convenient to create a jagged array rather than a rectangular array so you can manipulate the rows as a whole rather than using iteration.
