Base64 Conversions and CPU Usage

[Guest]

I'm reading a bytes of jpg file and convert them to Base64 string using
Sender Side : Convert.ToBase64String();
in Reciever Side : i get back the string to bytes i write it to file (i
convert the string to bytes using Convert.FromBase64String())

the CPU usage when Convert.FromBase64String() the CPU usage be within
80%~100% ,so i wondering are there more efficient ways to to such task?

hi Raed,
is that via a web service?
if so, you can send the bytes as a parameter (byte[]) to the web method, no
need to convert to and from a string.
or, if you want even better performance, you can look into using the Web
Service Enhancements (WSE) and send the file as a Dime attachment, which is
sent as raw binary attachment with a web method. (even the byte[] in a
normal web method gets serialised with XML, so lots of padding and
processing there still). there are webservices and webServiceEnhancements
newsgroups if that's the route you are going, which will help should you
have further questions.

hope this helps
