Convert list of bytes to byte array

I'm getting this error: Value of type 'System.Collections.Generic.List(Of Byte)' cannot be converted to '1-dimensional array of Byte'."

Form this code: (below)

I understand the error, I just don't know how to implement a fix.

Dim bt As String = contents

        Dim test As New List(Of Byte)()
        Dim pointer As Integer = 0
        While pointer < bt.Length
            Dim move As Integer = 3
            Dim temp1 As String = bt.Substring(pointer, 3)
            If Convert.ToInt32(temp1) > 255 Then
                temp1 = bt.Substring(pointer, 2)
                move = 2
            End If
            pointer += move + 1
        End While
        My.Computer.FileSystem.WriteAllBytes("C:\MyDocuments\CustomerData", test, True)

    My.Computer.FileSystem.WriteAllBytes("C:\MyDocuments\CustomerData", test, True)


    My.Computer.FileSystem.WriteAllBytes("C:\MyDocuments\CustomerData", test.ToArray, True)

The change was:

    test --> test.ToArray

I have tried that already and I get another error.  VB wants a byte array for the "WriteAllBytes"  code, but I created a list of bytes above.

...and what error are you getting now?

"VB wants a byte array for the "WriteAllBytes"  code, but I created a list of bytes above."

Right...ToArray() creates a byte array from your List!
