示例2: Main

Public Module Example
   Public Sub Main()
      Dim temp1 As New Temperature(100)
      Dim formats() As String = { "C", "G", "F", "K" } 

      ' Call Display method with a string array.
      Console.WriteLine("Calling Display with a string array:")
      temp1.Display(formats)
      Console.WriteLine()
      
      ' Call Display method with individual string arguments.
      Console.WriteLine("Calling Display with individual arguments:")
      temp1.Display("C", "F", "K", "G")
      Console.WriteLine()
      
      ' Call parameterless Display method.
      Console.WriteLine("Calling Display with an implicit parameter array:")
      temp1.Display()
   End Sub
End Module
