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
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
