How to add items/elements to an existing jagged array in C#?
To add an element to existing jagged array, just set the value of the element with a new value.
Let’s say you need to add an element at the following location −
a[3][1]
Just set the value −
a[3][1] = 500;
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[][] x = new int[][]{new int[]{10,20},new int[]{30,40}, new int[]{50,60},new int[]{ 70, 80 }, new int[]{ 90, 100 } };
int i, j;
Console.WriteLine("Old Array...");
for (i = 0; i < 5; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0}][{1}] = {2}", i, j, x[i][j]);
}
}
x[3][1] = 500;
Console.WriteLine("New Array...");
for (i = 0; i < 5; i++) {
for (j = 0; j < 2; j++) {
Console.WriteLine("a[{0}][{1}] = {2}", i, j, x[i][j]);
}
}
Console.ReadKey();
}
}
}
