服务器端：

首先把需要的东西放到一个可以序列化的类中。序列化成Xml，输出出来。

客户端：

获取这个Xml，反序列化就好。

两个问题：

1、数据量太大。

2、安全问题。

解决这些问题：

1、压缩后再传输。

压缩方法和解压方法：

        public static string Zip(string value)
        {
            byte[] buffer = Encoding.UTF8.GetBytes(value);
            System.IO.MemoryStream ms = new System.IO.MemoryStream();
            using (System.IO.Compression.GZipStream zip = new System.IO.Compression.GZipStream(ms, System.IO.Compression.CompressionMode.Compress, true))
            {
                zip.Write(buffer, 0, buffer.Length);
            }

            ms.Position = 0;
            System.IO.MemoryStream outStream = new System.IO.MemoryStream();

            byte[] compressed = new byte[ms.Length];
            ms.Read(compressed, 0, compressed.Length);

            byte[] gzBuffer = new byte[compressed.Length + 4];
            System.Buffer.BlockCopy(compressed, 0, gzBuffer, 4, compressed.Length);
            System.Buffer.BlockCopy(BitConverter.GetBytes(buffer.Length), 0, gzBuffer, 0, 4);
            return Convert.ToBase64String(gzBuffer);

        }

        public static string UnZip(string value)
        {
            byte[] gzBuffer = Convert.FromBase64String(value);
            using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
            {
                int msgLength = BitConverter.ToInt32(gzBuffer, 0);
                ms.Write(gzBuffer, 4, (gzBuffer.Length - 4));

                byte[] buffer = new byte[msgLength];

                ms.Position = 0;
                using (System.IO.Compression.GZipStream zip = new System.IO.Compression.GZipStream(ms, System.IO.Compression.CompressionMode.Decompress))
                {
                    zip.Read(buffer, 0, buffer.Length);
                }

                return Encoding.UTF8.GetString(buffer);
            }
        }

2、加点儿盐什么的。
