Accessing Elements in Jagged Arrays

Recall that elements in multi-dimensional rectangular arrays are accessed using an indexer for each dimension, separated by a comma (,):

1 2 3 4

// Rectangular array int[,] nums1 = new int[2, 3]; nums1[0, 2] = 20;    // Accessing elements in rectangular array nums1[1, 1] = 21;

Elements in jagged arrays are accessed using an indexer for each dimension, but with each indexer enclosed in its own pair of square brackets:

1 2 3 4 5 6

// Jagged array int[][] nums2 = new int[2][]; nums2[0] = new int[3]; nums2[1] = new int[2]; nums2[0][1] = 11;    // Accessing elements in jagged array nums2[1][0] = 10;
