Hi,

I have a byte array read from a file using Stream IO, and containing a
mixture of 16-bit integers, strings, etc..

The problem: what is the best way to convert two byte sequences into 16-bit
integers in a way similar to what I used to do with C or C++ formatted IO?

Is there really no direct way to accomplish this without my having to write
my own formatted IO routines? Any help appreciated.

Thanks.

Lew,

You can use the static ToInt16 method on the BitConverter class to do
this.

Hope this helps.
 
Nicholas,

Thank you. Exactly what I needed.

On another issue, do you have any counterpart for the C 'Union' construct in
C#?

Lew,

There really isn't one. You could use the FieldOffset attribute, but
for really complex unions, you will probably have to do something custom.

I would look up the terms "union" and "FieldOffset" in groups.google.com
in order to see previous threads on this subject.

Nicholas,

Thanks. Good advice. I'll Google (Group) it. :-)
