∟Jagged Arrays

This section describes jagged arrays which contain arrays as elements.

A Jagged array is an array that contains arrays as elements. Here are some examples: 

// JaggedArrays.cs

using System;
class JaggedArrays {
   static void Main() {
      int[] a1 = new int[9]; // array of int
      int[,] a2 = new int[3,9]; // two dimensional array of int
      int[][] j1 = new int[9][]; // array of array of int
      int[][,] j2 = new int[9][,]; // array of two dimensional array
      int[,][] j3 = new int[3,9][]; // two dimensional array of array
      a1[5] = 5;
      a2[1,5] = 15;
      j1[0] = a1;
      j2[0] = a2;
      j3[0,0] = a1;
      Console.WriteLine("a1[5] = {0}", a1[5]);
      Console.WriteLine("a2[1,5] = {0}", a2[1,5]);
      Console.WriteLine("j1[0][5] = {0}", j1[0][5]);
      Console.WriteLine("j2[0][1,5] = {0}", j2[0][1,5]);
      Console.WriteLine("j3[0,0][5] = {0}", j3[0,0][5]);
   }
}

Output: 

a1[5] = 5
a2[1,5] = 15
j1[0][5] = 5
j2[0][1,5] = 15
j3[0,0][5] = 5
