Hi Erick, hmm... this is interesting. I wouldn't have to worry about constantly expanding the byte array, and in this case I don't need to worry about accessing any internal bytes, just the end of the overall byte array to check for terminating characters.
(thinking out loud) I wonder if even something quick and dirty of an ArrayList of byte arrays would work? Simply as a quick prototype? Cheers!

A list just won't cut it with this size. I would suggest a new class that uses a list of byte[], and then uses the length of the internal byte array to determine the right array to touch in the indexer. I have to head out of the office, but I could throw together some code later if you need me to. It makes random access slower, but then you don't need to ever copy the data until the final step when you spit out the array, which should speed it up a lot. > > Erick > > > > > -----Original Message----- > > From: Discussion of advanced .NET topics. > > [mailto:[EMAIL PROTECTED] On Behalf Of > > gregory young > > Sent: Thursday, July 06, 2006 1:00 PM > > To: ADVANCED-DOTNET@DISCUSS.DEVELOP.COM > > Subject: Re: [ADVANCED-DOTNET] trim byte array > > > > Dave this is how list<byte> would work as well ... you can > > however set an initial size if you know it to avoid these doublings. > > > > Cheers, > > > > Greg > > > > > > On 7/6/06, dave wanta <[EMAIL PROTECTED]> wrote: > > > > > > Hi all, > > > > > > btw, just fyi...if you Reflector a MemoryStream, it doubles it's > > > internal buffer every time it exceeds it's length. > > > > > > The MemoryStream is really clean from a programmatic > > standpoint, it's > > > just not the performance I really want. > > > > > > Thanks for all the suggestions guys!
