Hi.  I'm trying to compress a folder (and it's subdirectories).  I've adapted code I've found on the net which zip's up the files within the folder specified, but not the sub-folders (ie, the entire contents).

Here's the code:
---------
string[] filenames = Directory.GetFiles(str_vledatasource.Text);
using (ZipOutputStream s = new ZipOutputStream(File.Create(str_vledatadestination.Text+"\\VLE Backup ("+ strTimeStamp.ToString()+").zip")))
                {

                    s.SetLevel(9); // 0-9, 9 being the highest compression
                    byte[] buffer = new byte[4096];

                    foreach (string file in filenames)
                    {
                        ZipEntry entry = new
                        ZipEntry(Path.GetFileName(file));
                        entry.DateTime = DateTime.Now;
                        s.PutNextEntry(entry);
                        using (FileStream fs = File.OpenRead(file))

                      {

                            int sourceBytes;
                            do
                            {

                               sourceBytes = fs.Read(buffer, 0, buffer.Length);
                               s.Write(buffer, 0, sourceBytes);
                            }

                            while (sourceBytes > 0);
                        }

                    }

                    s.Finish();
                    s.Close();

Can anyone help me finish this off, please?
str_vledatasource.Text is the string for the location
str_vledatadestination.Text is the string for the output/destination of the zip.
Thanks.
