How do I convert a byte array in to a 32bit integer array

Hi there,

I am writing an application where I need to return 16 digits to the user as product code.One of my objects returns a byte array of length 128. I need to convert these 128 bytes in to 16 digits.I am trying to achieve this as follows:-

Dim reg As New regProcess<br />
        Dim ProductCode As Byte()<br />
        Dim i As Integer = 0<br />
        Dim j As Integer = 0<br />
        Dim num As UInt64 = 0<br />
<br />
        ProductCode = reg.Register<br />
        If ProductCode.Length > 0 Then<br />
            txt_ProductCode.Text = ""<br />
            <br />
            While i < (ProductCode.Length / 8)<br />
                Dim var As UInt64 = 0<br />
                For j = 0 To 7<br />
                    var += Convert.ToUInt64(ProductCode(i))<br />
<br />
                    i += 1<br />
                Next<br />
                 txt_ProductCode.Text += Convert.ToString(var)<br />
               <br />
            End While<br />
        End If<br />
 End Sub

This doesn't guarantee to return 16 digits as I am taking the sum of 8 consecutive bytes.

My question is can anybody tell me how do I interpret those 128 bytes as 32 bit integers, so that I can display 16 digits as product code.
Any help is appreciated.
