How to access elements from jagged array in C#?
A Jagged array is an array of arrays. To access an element from it, just mention the index for that particular array.
Here, we have a jagged array with 5 array of integers −
int[][] a = new int[][]{new int[]{0,0},new int[]{1,2}, new int[]{2,4},new int[]{ 3, 6 }, new int[]{ 4, 8 } };Let’s say you need to access an element from the 3rd array of integers, for that −
a[2][1]
Above, we accessed the first element of the 3rd array in a jagged array.
Let us see the complete code −
Example
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
int[][] a = new int[][]{new int[]{0,0},new int[]{1,2}, new int[]{2,4},new int[]{ 3, 6 }, new int[]{ 4, 8 } };
int i, j;
for (i = 0; i < 5; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0}][{1}] = {2}", i, j, a[i][j]);
}
}
// accessing element from a jagged array
Console.WriteLine(a[2][1]);
Console.ReadKey();
}
}
}
