basically, the method returns a system.array object

the data is like :

(1) = 255
(2) = 216
(3) = 255

etc etc

when i try to cast it put it in a memory stream like this:

Dim str As System.IO.MemoryStream = New System.IO.MemoryStream(arr)

it gives me an error:

System.InvalidCastException = {"Unable to cast object of type 'System.Byte[*]' to type 'System.Byte[]'."}

 Any ideas?
