You have a few options:
 * The old std.stream -- this module is due for replacement, hopefully 
ASAP.
 * Use File.rawRead/rawWrite.  These are intended for arrays, though they 
can be used to read single values.
 * Work with chunks of ubyte data and use std.bitmanip's read and write 
functions.

The last option is probably your best option for producing good future-
proof, idiomatic D code.
