Issue with Lists

[MotoMan_Yz400]

I have 2 lists, SortedValuesA and SortedValuesB.

Heres the code I have a problem with.....

Dim SortedValuesb As New List(Of String())
 Dim SortedValuesa As New List(Of String())
.
.
.
'I assign a 28 arrays to List SortedValuesa
'Pull some out of A and add to B
.
.
.
   SortedValuesa = SortedValuesb
   MsgBox(SortedValuesa.Count)
   SortedValuesb.Clear()
   MsgBox(SortedValuesa.Count)

Now when this runs, the fist MSGBOX gives me 18, which is correct. Now the second MSGBOX gives me 0.... Thats my problem.

By saying A=B they are now linked? So clearing B will clear A? How do I fix this?

I'm using B as a buffer to hold temporary values pulled from A. The next step beyond this code is to do a few more layers of "stripping" until I have the final arrays that I need.
