Unzip and DeSerialize
 

public T UnzipAndDeserialize(string zipFileName)
    {
        FileStream compressedStream = new FileInfo(zipFileName).OpenRead();
        MemoryStream destinationStream = new MemoryStream();
        GZipStream gzipStream = new GZipStream(compressedStream, CompressionMode.Decompress);
        byte[] buffer = new byte[4096];

        int numRead;

        while ((numRead = gzipStream.Read(buffer, 0, buffer.Length)) != 0)
        {
            destinationStream.Capacity += numRead;
            destinationStream.Write(buffer, 0, numRead);
        }

        gzipStream.Dispose();
        compressedStream.Dispose();

        destinationStream.Position = 0;

        XmlSerializer deserializer = new XmlSerializer(typeof(T));
        T result = (T)deserializer.Deserialize(destinationStream);

        return result;
    }
