Dim numbersToConvert() As Long = { 162345, 32183, -54000, Int64.MaxValue\2 }
Dim newNumber As Integer
For Each number As Long In NumbersToConvert
   If number >= Int32.MinValue And number <= Int32.MaxValue Then
      newNumber = Convert.ToInt32(number)
      Console.WriteLine("Successfully converted {0} to an Int32.", _
                        newNumber)
   Else
      Console.WriteLine("Unable to convert {0} to an Int32.", number)
   End If                     
Next
