Please try below, based on this url : http://dreamstatecoding.blogspot.com/2013/04/c-array-compress-and-decompress-with.html. We avoid to use double MemoryStream.

    public static byte[] Compress(string text)
    {
        var bytes = Encoding.Unicode.GetBytes(text);
        using (var mso = new MemoryStream())
        {
            using (var gs = new GZipStream(mso, CompressionMode.Compress))
            {
                gs.Write(bytes, 0, bytes.Length);
            }
            return mso.ToArray();
        }
    }

    public static string Decompress(byte[] data)
    {
        // Read the last 4 bytes to get the length
        byte[] lengthBuffer = new byte[4];
        Array.Copy(data, data.Length - 4, lengthBuffer, 0, 4);
        int uncompressedSize = BitConverter.ToInt32(lengthBuffer, 0);

        var buffer = new byte[uncompressedSize];
        using (var ms = new MemoryStream(data))
        {
            using (var gzip = new GZipStream(ms, CompressionMode.Decompress))
            {
                gzip.Read(buffer, 0, uncompressedSize);
            }
        }
        return Encoding.Unicode.GetString(buffer);            
    }
