Appending arrays - HOWTO? 1

[IlyaRabyy]

Colleagues,
Can't recall if I've asked this Q. B 4, forgive me if I had.

Say, you have two arrays of the same data type, and you need to add/concatenate/append them into one.
Besides the obvious (ReDim Preserve one array with the sum of elements and copy the elements of the second one to the empty sells of the first one) -
is there a function in the .NET that does exactly that? Something like (tried, dinna work)

Dim la1() As String = {"1", "2", "3"}
Dim la2() As String = {"4", "5", "6"}

Dim laS() As String = la1 & la2 ' Erred, "[COLOR=#CC0000]Error	BC30452	Operator '&' is not defined for types 'String()' and 'String()'[/color]"

(I ran the search in MS .NET Help, found nothing helpful...)

Regards,

Ilya

Have you tried something like this?

Dim la1() As String = {"1", "2", "3"}
Dim la2() As String = {"4", "5", "6"}
Dim laS() As String = la1.Concat(la2).ToArray()

or

Dim la1() As String = {"1", "2", "3"}
Dim la2() As String = {"4", "5", "6"}
Dim laS(la1.Length + la2.Length - 1) As String
la1.CopyTo(laS, 0)
la2.CopyTo(laS, la1.Length)

or

Dim la1() As String = {"1", "2", "3"}
Dim la2() As String = {"4", "5", "6"}
Dim laS(la1.Length + la2.Length - 1) As String
Array.Copy(la1, laS, la1.Length)
Array.Copy(la2, 0, laS, la1.Length, la2.Length)

I like this Concat() the best! , StrongM!

Actually, I need to concatenate 3 arrays, so I tried (C/C++ style, y'kno)

Dim la1() As String = {"1", "2", "3"}
Dim la2() As String = {"4", "5", "6"}
Dim la3() As String = {"7", "8", "9"}
Dim laS() As String = la3.Concat(la1.Concat(la2).ToArray()).ToArray()

and it worked!

Regards,

Ilya
