C# Examples: Jagged Arrays

 

Introduction

This example uses various variables that each represents an array of arrays, also called jagged arrays:

using System;

class DepartmentStore
{
	static int Main()
	{
		// Each of the following variable arrays is structured as [2][2][4].
		// Each variable represents:
		// A/ Two major lists: The first major list represents women items,
		//				       the second major list represents men items,
		// B/ Two minor lists.
		//    Each of the major lists contains two minor lists:
		//	  a/ The first minor list of the first major list contains adult women items
		//		 The second minor list of the first major list contains girls items
		//	  b/ The first minor list of the second major list contains adult men items
		//		 The second minor list of the second major list contains boys items
		// C/ Each minor list contains four items
