What is a jagged array in C#?

Jagged array is an array of arrays in C#. You can declare and initialize it -

int[][] rank = new int[1][]{new int[]{5,3,1}};

The following example shows how to use jagged array in C#-

Example

using System;

namespace Program {
   class Demo {
      static void Main(string[] args) {

         int[][] rank = new int[][]{new int[]{1,2},new int[]{3,4}};
         int i, j;

         for (i = 0; i < 2; i++) {
            for (j = 0; j < 2; j++) {
               Console.WriteLine("a[{0}][{1}] = {2}", i, j, rank[i][j]);
            }
         }
         Console.ReadKey();
      }
   }
}

Output

Above, We have a jagged array of 2 integer arrays -

int[][] rank = new int[][]{new int[]{1,2},new int[]{3,4}};
