byte[] bytes = myclient.GetDataAndIAQI0320("北京", "");
//以下为偏移四个字节
MemoryStream ms = new MemoryStream(bytes, 4, bytes.Length-4 );
string str2 = DecompressString(ms.ToArray());


以下为deflateStream函数:
        /// <summary>  
        /// 解压字符串  
        /// </summary>  
        /// <param name="str"></param>  
        /// <returns></returns>  
        public static string DecompressString(byte[] str)
        {
            return Encoding.UTF8.GetString(DecompressBytes(str));
        }
        /// <summary>  
        /// 解压二进制  
        /// </summary>  
        /// <param name="str"></param>  
        /// <returns></returns>  
        public static byte[] DecompressBytes(byte[] str)
        {
            var ms = new MemoryStream(str) { Position = 0 };
            var outms = new MemoryStream();
            using (var deflateStream = new DeflateStream(ms, CompressionMode.Decompress, true))
            {
                var buf = new byte[1024];
                int len;
                while ((len = deflateStream.Read(buf, 0, buf.Length)) > 0)
                    outms.Write(buf, 0, len);
            }
            return outms.ToArray();
        }  
但是运行的时候报错，错误提示为：块的长度与它的补集不匹配。
