How do you access jagged arrays in C#?

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

int x = points[0][1];

The following is the complete example showing how to access jagged arrays in C#.

Example

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]);
            }
         }
         // access
         int x = points[0][1];
         Console.WriteLine(x);
         Console.ReadKey();
      }
   }
}
