Data Strcutures using C#

Arrays serve as a popular homogenous uniform-sized direct access data structure. Well not all array elements need be uniform length. Jagged arrays are arrays of arrays where the contained arrays could be of variable length.  These are declared as follows:
int[][] jaggedArray = new int[3][];
jaggedArray[0] = new int[] { 1, 3, 5, 7, 9 };
jaggedArray[1] = new int[] { 0, 2, 4, 6 };
jaggedArray[2] = new int[] { 11, 22 };
A multidimensional array on the other hand is declared as follows:
int[,] multiArray = new int[,]
{ {1 ,2, 3}, {4, 5, 6}, {7, 8, 9|}}
