Hi,

I wrote a piece of sw that is getting data from a device.
I'm storing the data in binary files in a specific folder. Each 5MB, I create a new binary.

For the moment, I filling this directory, and when I stop getting data, I launch zip process that takes all binary files one by one and copy them in the archive.

My concern is it's taking too much time (I need to zip 500-600 files of 5MB). What I do:

archive.BeginUpdate();
foreach (AbstractFile file in sourceFolder.GetFiles(true, null))
{
    i++;
    MainForm.SetStatusMessage("Closing ZIP... (Archiving " + i + " of " + nbOfFiles.ToString() + ")");
    file.CopyTo(archive, true);
}
archive.EndUpdate();

 
where archive is a ZipArchive object.

 
I would like to improve my algorithm starting the sippage while getting data:

Each time I receive a binary, I do :

archive.BeginUpdate();
DiskFile file = new DiskFile(pFileName);
file.CopyTo(archive, true);
archive.EndUpdate();

It's good for the first 20 binary files, but when we reach the 100th file, the copy to the archive is taking to much cpu and time.

How can I do with Xceed component to generate this ZIP file in real time ?

Thanks

If you do not need to manipulate the archive in between adding new files until the whole archive is constructed, then you should use Real-Time Zip for .NET.  It will zip your stream as it is coming it.

e.g.:

ZipWriter( Stream outputStream )

WriteLocalHeader, WriteData

  WeiteLocalHeader, WriteData

   ...( for each file)

ZipWriter.Close()

You can read more in the documentation on how to use this :
