How do you initialize jagged arrays in C#?

A Jagged array is an array of arrays. This is how you can initialize it.

int[][] rank = new int[2][]{new int[]{3,2,7},new int[]{9,4,5,6}};

The following is an example showing how to initialize jagged arrays in C#.

Example

 Live Demo

using System;
namespace ArrayApplication {
   class MyArray {
      static void Main(string[] args) {
         int[][] a = new int[][]{new int[]{0,0},new int[]{1,2}, new int[]{2,4} };
         int i, j;
         for (i = 0; i < 3; i++) {
            for (j = 0; j < 2; j++) {
               Console.WriteLine("a[{0}][{1}] = {2}", i, j, a[i][j]);
            }
         }
         Console.ReadKey();
      }
   }
}

Output

a[0][0] = 0
a[0][1] = 0
a[1][0] = 1
a[1][1] = 2
a[2][0] = 2
a[2][1] = 4
