file stream

Is it possible to use this code to view a BLOB in the db. The file not in my harddrive and I'm having a problem converting a Byte()array to a string?

Code:

---

Dim strFileName As String = ("C:\index.pdf")
Dim objStream As Stream = File.Open(strFileName, FileMode.Open)
Dim buffer(objStream.Length) As Byte
objStream.Read(buffer, 0, objStream.Length)
objStream.Close()

---

This function will return a string when given a byte array:

Public Function ByteArrayToString(ByVal bytArray() As Byte) As String
Dim UTF8 As New UTF8Encoding()
Return UTF8.GetString(bytArray)
End Function

thanks IOU...I didn't end up needing to convert the Byte array...I used:

Code:

---

Do While objDR.Read = True
                Dim pdf As String = "bid_package.pdf"
                Response.Clear()
                Response.ContentType = "application/octet-stream"
                Response.AddHeader("Content-Disposition", "attachment;filename=" & Trim(pdf))
                Response.BinaryWrite(objDR("bid_document"))
                Response.Flush()
                Response.End()
            Loop

but I'm going to save that piece of code..thanks
