How to clone Array within a Class ? ?? ?


Unbelievable :

I have a class :

Public Class ClassLine

    Private m_Name As String
    Private m_ArrayY As Double()

   Public Function ShallowCopy() As ClassLine   ' this lets to clone the details of a class, but NOT a REFERENCE !
        Return Me.MemberwiseClone
    End Function

end class

(See this to understand ShallowCopy:

Well...If I use this on the form:

Dim L1 As ClassLine = L.ShallowCopy

All is cloned ok, except the ARRAY !

That's it :

If I have : "Rufus"
and I have cloned on L1, after do the shallow copy I can do:"pipo", and is still with : "Rufus"

But is I modify the Array, the data is also modified on L1 .... WHY ? ? ?

How can I solve it  ? ?

I tried this :

L1.ArrayY = L.ArrayY
L1.Name = L.Name

and this :

 Dim ArrayTemp() As Double = L.ArrayY
        For i = 0 To UBound(L.ArrayY)
            ArrayTemp(i) = L.ArrayY(i)

        L1.ArrayY = ArrayTemp

But still the same reference....

Any ideas ? ? ?

Hey ! I achieved that :

This works :

Dim ArrayTemp() As Double
        ReDim ArrayTemp(UBound(L.ArrayY))
        For i = 0 To UBound(L.ArrayY)
            ArrayTemp(i) = L.ArrayY(i)

        L1.ArrayY = ArrayTemp

But...any idea of doing this more elegant = ? ?? ??

Bye !!

Hello franklinan,

you could look at

ArrayTemp = L.ArrayY.Clone


hope this helps a bit
