Property.

[shapper]

Hello,

On my profile I have a property as follows:

Private _Levels As Generic.List(Of Enumeration.Level)
Public Property Levels() As Generic.List(Of Enumeration.Level)
Get
If _Levels Is Nothing Then
Return New Generic.List(Of Enumeration.Level)
End If
Return _Levels
End Get
Set(ByVal value As Generic.List(Of Enumeration.Level))
_Levels = value
End Set
End Property ' Levels

When I create a new profile I don't add any items to this property ...
only later.
However when later I try to add items they are not added.

The only way to make this work is to, when I create the profile for
the new user, the following:
Profile.Levels = New Generic.List(Of Level)

Just like an initialization.

Well, do I really need to do that?
Maybe my property is not completely right ...

Should I change something in my property?

Thanks,
Miguel

shapper,

you need to correct your code to make it work:
Get
If _Levels Is Nothing Then
' in the next line change Return to _Levels =
_Levels = New Generic.List(Of Enumeration.Level)
End If
Return _Levels
End Get

Why do you think that they are not added? What have you done to come to
this conclusion?

That doesn't have anything to do with the problem. It makes the property
return the same empty list instead of creating a new one every time if
the property is read multiple times before it's set, so it's not a bad
thing to do, but it's not relevant for the question.
