Process An Array With The foreach Loop

You  can use the following code to declare an array called Numbers, and process an array with the foreach statement, and write the values to the console, one line at the time:

        Module Module1
               Sub Main()
                    Dim Numbers As Integer() = {4, 3, 2, 1, 0, -1, -2, 9, 5}
                    Console.WriteLine("The contents of an array is :")
                    For Each K As Integer In Numbers
                    Console.Write("{0}" & vb Tab, K)
                    Next
                    Console.ReadLine()
              End Sub
       End Module

The output of the preceding code is as follows:
