Serializing data types for use over a network in F#

I want to send a a Uint16 over the network. I've had a look at the different .NET serializers available. According to this F# Serialize Discriminated Union why so many bytes? using a BinaryFormatter will generate overhead bytes that represent meta-data for that type. A result of this would be that UInt16, once passed through that formatter, may not be represented as 16 bits. I need a way to convert that UInt16 such that I get 16 bits from it that I can send to the program at the other end of the socke开发者_运维技巧t.

I think you can use System.BitConverter class:

static member GetBytes : 
        value:uint16 -> byte[]

I just found the BitConverter class and it looks like it does what I want:

byte_array = BitConverter.GetBytes header.id

where header.id is UInt16
