4.2. Understanding C# Arrays

As I would guess you are already aware, an array is a set of data items, accessed using a numerical index. More specifically, an array is a set of contiguous data points of the same type (an array of ints, an array of strings, an array of SportsCars, and so on). Declaring an array with C# is quite straightforward. To illustrate, create a new Console Application project (named FunWithArrays) that contains a helper method named SimpleArrays(), invoked from within Main():

class Program
{
  static void Main(string[] args)
  {
    Console.WriteLine("***** Fun with Arrays *****");
    SimpleArrays();
    Console.ReadLine();
  }

  static void SimpleArrays()
  {
    Console.WriteLine("=> Simple Array Creation.");
    // Assign an array of ints containing 3 elements {0, 1, 2}
    int[] myInts = new int[3];

    // Initialize a 100 item string array, indexed {0 - 99}
    string[] booksOnDotNet = new string[100];
    Console.WriteLine();
  }
}
