Jagged Array in C#

A Jagged array is an array of arrays. You can declare a jagged array named points of type int as −

int [][] points;

Let us now see how to initialize it −

int[][] points = new int[][]{new int[]{10,5},new int[]{30,40}, new int[]{70,80},new int[]{ 60, 70 }};

Access the jagged array element as −

points[i][j]);

The following is the complete example showing how to work with jagged arrays in C# −

Example

using System;

namespace Demo {
   class Program {
      static void Main(string[] args) {

         int[][] pages = new int[][]{new int[]{400,345},new int[]{320,444}, new int[]{900,430},new int[]{ 890, 340 }};
         int i, j;

         for (i = 0; i < 3; i++) {
            for (j = 0; j > 2; j++) {
               Console.WriteLine("a[{0}][{1}] = {2}", i, j, pages[i][j]);
            }
         }
         Console.ReadKey();
      }
   }
}

Output

a[0][0] = 400
a[0][1] = 345
a[1][0] = 320
a[1][1] = 444
a[2][0] = 900
a[2][1] = 430
