How to convert from System.Int32 to System.UInt16 in F#

Is there a better (sho开发者_运维知识库rter?) way than the following?

let cpucount = System.UInt16.Parse( reader.GetInt32(3).ToString() )

let i = uint16 42

and the 'casts' section of

What does this C# code look like in F#?

I don't know F#, but you could write Convert.ToUint16(reader.GetInt32(3)).

EDIT: According to MSDN, you can cast by writing uint16 reader.GetInt32(3).
