Writes primitive types in binary to a stream and supports writing strings in a specific encoding.

System.Object
  System.IO.BinaryWriter

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

[<SerializableAttribute>]
[<ComVisibleAttribute(true)>]
type BinaryWriter =  
    class
        interface IDisposable
    end

The BinaryWriter type exposes the following members.
