最近在测试通讯模块时，发现新增的Android平台发送过来的数据，服务器端总是收不到，后来发现java中数据类型有些和C#中的不一样，比如C#中byte对应范围是0~255，而Java中则对应的是-128~127,因此直接按照通讯协议传序列化的二进制流总是出现问题。考虑到这一点在Android那一端才用Joson序列化发送到服务端，而在服务端对接收到的数据进行反序列化后转化为对象。同时在服务端进行发送数据时，转换为Joson格式后，序列化为二进制流发生给Android端。

废话不多说了，上代码:

//Joson格式的二进制流转换为对象

public static T JosonDeSerializer<T>(byte[] buffer, int length)
        {
            try
            {
                string mTextReceived = Encoding.UTF8.GetString(buffer, 0, length);

//将获取到的Joson格式字符串转换为数据包类
                SocketDataPack sdp = GetSocketDataPackFromString(mTextReceived);
                MemoryStream stream = new MemoryStream();
                BinaryFormatter formatter = new BinaryFormatter();

//将数据包类序列化
                formatter.Serialize(stream, sdp);
                stream.Position = 0;
                stream.Flush();

//转换为对象
                object obj = formatter.Deserialize(stream);
                if (obj == null)
                {
                    return default(T);
                }
                return (T)obj;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
        //对象转换为Joson格式二进制流
        public static byte[] JosonSerializer(object input)
        {
            try
            {
                JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
                string strSocketDataPack = jsonSerializer.Serialize(input);
                byte[] buffer = Encoding.UTF8.GetBytes(strSocketDataPack);
                return buffer;
            }
            catch (Exception ex)
            {
                throw ex;
            }

}

        private static SocketDataPack GetSocketDataPackFromString(string context)

                SocketDataPack sdp = new SocketDataPack();
                context = context.Replace("{", "").Replace("[", "").Replace("]", "").Replace("}", "").Replace("\"", "").Replace("\0","");
                String[] str = context.Split(',');
