Arrays in C#

A code snippet that creates a minimal array in C#:

using System;

class MyArray
  static void Main(string[] args)
    int[] myArray = new int[4];
    int i = 0;

    foreach (int a in myArray)
      Console.WriteLine("item {0} has value {1}", i++, a);

Compile it and the not so sexy output is:

 item 0 has value 0
 item 1 has value 0
 item 2 has value 0
 item 3 has value 0

Visual Basic .NET

The corresponding example in Visual Basic should be something like this:

Module myVisualBasicArray

  Sub Main()
    Dim myArr(4) As Integer
    Dim i As Integer = 0

    Do While (i < myArr.Length)
      Console.WriteLine("item in position {0} is {1}", i, myArr(i))
      i += 1

  End Sub

End Module

The output is similar, but not identical

item in position 0 is 0
item in position 1 is 0
item in position 2 is 0
item in position 3 is 0
item in position 4 is 0


Allocating arrays in Visual Basic is done with the number of the largest index one wants to access, not the number of elements in the array.
