c# jagged arrays

A jagged array is an array whose elements are arrays. The elements of a jagged array can be of different dimensions and sizes. A jagged array is sometimes called an "array of arrays." The following examples show how to declare, initialize, and access jagged arrays.

int[][] arr = new int[2][];
// Initialize the elements:
arr[0] = new int[5] { 1, 3, 5, 7, 9, 11 , 13 };
arr[1] = new int[4] { 2, 4, 6, 8 , 10, 12 };
// Display the array elements:
for (int i = 0; i < arr.Length; i++)
{
System.Console.Write("Element({0}): ", i);
for (int j = 0; j < arr[i].Length; j++)
{
System.Console.Write("{0}{1}", arr[i][j], j == (arr[i].Length - 1) ? "" : " ");
}
System.Console.WriteLine();
}
// Keep the console window open in debug mode.
System.Console.WriteLine("Press any key to exit.");
System.Console.ReadKey();
/*
Output: Element(0): 1 3 5 7 9 11 13
Element(1): 2 4 6 8 10 12
