If the serial number is stored in a string, use the .substring command to extract the pieces of the id.

Dim arrOfBytes As Byte(8)
arrOfBytes(0) = Byte.Parse(Serial.substring(1,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(1) = Byte.Parse(Serial.substring(3,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(2) = Byte.Parse(Serial.substring(5,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(3) = Byte.Parse(Serial.substring(7,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(4) = Byte.Parse(Serial.substring(10,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(5) = Byte.Parse(Serial.substring(12,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(6) = Byte.Parse(Serial.substring(14,2), Globalization.NumberStyles.HexNumber)
arrOfBytes(7) = Byte.Parse(Serial.substring(16,2), Globalization.NumberStyles.HexNumber)

Dim arrOfBytes(8) As Byte

I couldn't remember the exact syntax for VB.Net. I'm sure you figured it out on your own though.
