How do you declare, initialize and access jagged arrays in C#?

Declare Jagged Array

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

int [][] points;

Initialize Jagged Array

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

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

 Live Demo

using System;
namespace ArrayApplication {
   class MyArray {
      static void Main(string[] args) {
         int[][] points = new int[][]{new int[]{10,5},new int[]{30,40}, new int[]{70,80},new int[]{             60, 70 }};
         int i, j;
         for (i = 0; i < 3; i++) {
            for (j = 0; j < 2; j++) {
               Console.WriteLine("a[{0}][{1}] = {2}", i, j, points[i][j]);
            }
         }
         Console.ReadKey();
      }
   }
}

Output

a[0][0] = 10
a[0][1] = 5
a[1][0] = 30
a[1][1] = 40
a[2][0] = 70
a[2][1] = 80
