aspx_beginners thread: Parameters on accessor method "Get"

I am using the book Beginning ASP.NET 1.0 with VB.NET (ISBN: 1-861007-33-
7). Below is a modified version of the car_object_overload.aspx program
from chapter 8 in which I specified a parameter on the Get accessor
method for the Color property. (The parameter says what language to
return the color in.) The chapter did not show any examples of doing
this, but Exercise 4 at the end of the chapter says the
following: "Define a new property ConvPrice, whose accessor method Get
takes two parameters denoting...". I assume from this that this is
legal, yet when I tried it, I generated the following error:
Compiler Error Message: BC30124: Property without a 'ReadOnly'
or 'WriteOnly' specifier must provide both a 'Get' and a 'Set'.
Source Error:
Line 7: Private _Gear As Integer
Line 8:
Line 9: Public Property Color As String
Line 10: Get(lang as String)
Line 11: If lang = "French" Then
Here is the relevant portion of the program that generated the error:
Public Class Car
Private _Color As String
Public Property Color As String
Get(lang as String)
If lang = "French" Then
Select Case _Color
Case "Blue"
Return "Bleu"
Case "Green"
Return "Vert"
Case "White"
Return "Blanche"
Case Else
Return "Mon dieu! Je ne sais pas."
End Select
Else
Return _Color
End If
End Get
Set(value as String)
_Color = value
End Set
End Property
End Class
Sub Page_Load()
Dim MyCar as New Car()
MyCar.Color = "White"
Response.Write("Color: " & MyCar.Color("French"))
End Sub
What is wrong?

I'm pretty new to .Net too, but the problem I see in this example is not
the syntax of what you're doing, it's *what you're doing*.
Isn't the 'pure' object based model one where you'd have an absolute
value for the colour (with standard get and set methods) and then an
*additional* method to return the localized string that tells the colour
in one of a set of recognised languages?
