Silverlight compressed binary serialization

So... I did my first Silverlight app - very good fun (although there was a fair amount of head scratching too!)

As part of this app I needed to send some fairly chunky bits of data to the client. To do this I used http://whydoidoit.com/silverlight-serializer/ and http://slsharpziplib.codeplex.com/

On the server (in an offline process) the code that generated my compressed files looked like:

            using (var f = File.Create(zipFileName))

            {

                using (var zipOut = new ZipOutputStream(f))

                {

                    ZipEntry entry = new ZipEntry("stuff");

                    var toStore = Serialization.SilverlightSerializer.Serialize(myClass);

                    entry.DateTime = DateTime.Now;

                    entry.Size = toStore.Length;

                    zipOut.PutNextEntry(entry);

                    zipOut.Write(toStore, 0, toStore.Length);

                    zipOut.Finish();

                    zipOut.Close();

                }

            }

And in the Silverlight client the code looked like:

        public void LoadFrom(Uri url)

        {

            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);

            request.BeginGetResponse(new AsyncCallback(ReadCallback), request);

        }

        private void ReadCallback(IAsyncResult asynchronousResult)

        {

            HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;

            HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);

            using (ZipInputStream zipIn = new ZipInputStream(response.GetResponseStream()))

            {

                ZipEntry entry;

                if ((entry = zipIn.GetNextEntry()) != null)

                {

                    var myClass = Serialization.SilverlightSerializer.Deserialize<TheClass>(zipIn);

                    if (myClass == null)

                    {

                        MessageBox.Show("Some error has occurred - unable to read data - sorry!");

                        return;

                    }

                    Dispatcher.BeginInvoke(() =>

                        {

                           // do stuff with myClass here

                        });

                }

            }

        }

It all worked surprisingly well :)
