Deserialization, after GZipStream ,What is Wrong with it?

Question

Hi, everyone...

I have a Memorystream and put in a GZipStream, save in SQL 2005, after that I load this stream from sql 2005 and try to deserialize from BinaryFormatter. This will be the GOLD, for now I whant a simple serializable-Compress-Decompress-Deserializable objects is very very fine... I anyone could help-me I will be very gratefull...  I past the code I´m using, for traing to make it works... In the last line I´m reciveing an error:
"Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization."

Anyone have any tip ou anything maybe helps me with that??? THANKS A LOT IN ADVANCE!!!

My Code:

public static void Main()
            {

                List p3;
                List p1 = new List();
                p1.Add("Brazil");
                p1.Add("Error");
                p1.Add("Serializable");


                Stream Serial = new MemoryStream();
                FileStream fileStream = new FileStream("Teste.bin", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
                //BinaryFormatter teste = new BinaryFormatter();
                Processo _Retorno = new Processo();
                BinaryFormatter teste = new BinaryFormatter();
                teste.Serialize(Serial, p1);
                byte[] buffer = new byte[Serial.Length];
                Serial.Read(buffer, 0, buffer.Length);
                fileStream.Write(buffer, 0, buffer.Length);
                fileStream.Close();
                //teste.Serialize(fileStream, _Retorno );
                byte[] Compremido = Compressor.Compress(buffer);
                //FileStream destino = new FileStream("Teste.ZIP", FileMode.Create, FileAccess.ReadWrite, FileShare.None);
                //destino.Write(Compremido,0,Compremido.Length  );
                //destino.Close();
                byte[] Descompremido = Compressor.Decompress(Compremido);
                MemoryStream msUnZip = new MemoryStream();
                msUnZip.Write(Descompremido, 0, Descompremido.Length);
                msUnZip.Seek(0, SeekOrigin.Begin);
                BinaryFormatter Serializador = new BinaryFormatter();
                p3 = (List)Serializador.Deserialize(msUnZip);
                
            }

public static class Compressor
        {

            public static byte[] Compress(byte[] data)
            {
                MemoryStream output = new MemoryStream();
                GZipStream gzip = new GZipStream(output,
                                  CompressionMode.Compress, true);
                gzip.Write(data, 0, data.Length);
                gzip.Close();
                return output.ToArray();
            }

            public static byte[] Decompress(byte[] data)
            {
                MemoryStream input = new MemoryStream();
                input.Write(data, 0, data.Length);
                input.Position = 0;
                GZipStream gzip = new GZipStream(input,
                                  CompressionMode.Decompress, true);
                MemoryStream output = new MemoryStream();
                byte[] buff = new byte[64];
                int read = -1;
                read = gzip.Read(buff, 0, buff.Length);
                while (read > 0)
                {
                    output.Write(buff, 0, read);
                    read = gzip.Read(buff, 0, buff.Length);
                }
                gzip.Close();
                return output.ToArray();
            }
        }
