最近在測試通訊模塊時，發現新增的Android平臺發送過來的數據，服務器端總是收不到，后來發現java中數據類型有些和C#中的不一樣，比如C#中byte對應范圍是0~255，而Java中則對應的是-128~127,因此直接按照通訊協議傳序列化的二進制流總是出現問題。考慮到這一點在Android那一端才用Joson序列化發送到服務端，而在服務端對接收到的數據進行反序列化后轉化為對象。同時在服務端進行發送數據時，轉換為Joson格式后，序列化為二進制流發生給Android端。

廢話不多說了，上代碼:

//Joson格式的二進制流轉換為對象

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

??????????????? //將獲取到的Joson格式字符串轉換為數據包類
??????????????? SocketDataPack sdp = GetSocketDataPackFromString(mTextReceived);
??????????????? MemoryStream stream = new MemoryStream();
??????????????? BinaryFormatter formatter = new BinaryFormatter();

??????????????? //將數據包類序列化
??????????????? formatter.Serialize(stream, sdp);
??????????????? stream.Position = 0;
??????????????? stream.Flush();

??????????????? //轉換為對象
??????????????? object obj = formatter.Deserialize(stream);
??????????????? if (obj == null)
??????????????? {
??????????????????? return default(T);
??????????????? }
??????????????? return (T)obj;
??????????? }
??????????? catch (Exception ex)
??????????? {
??????????????? throw ex;
??????????? }
??????? }
??????? //對象轉換為Joson格式二進制流
??????? 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;
??????????? }

??????? }
??????? /// <summary>
??????? /// 將Json格式的字符串轉換為指定的數據包類
??????? /// </summary>
??????? /// <param name="context"></param>
??????? /// <returns></returns>
??????? private static SocketDataPack GetSocketDataPackFromString(string context)
??????? {
??????????? try
??????????? {
??????????????? SocketDataPack sdp = new SocketDataPack();
??????????????? context = context.Replace("{", "").Replace("[", "").Replace("]", "").Replace("}", "").Replace("\"", "").Replace("\0","");
??????????????? String[] str = context.Split(',');
??????????????? for (int i = 0; i < str.Length; i++)
??????????????? {
??????????????????? String[] str2 = str[i].Split(':');
??????????????????? switch (str2[0])
??????????????????? {
??????????????????????? case "Length":
??????????????????????????? sdp.Length = Convert.ToInt16(str2[1]);
??????????????????????????? break;
??????????????????????? case "Head":
??????????????????????????? sdp.Head = Convert.ToByte(str2[1]);
??????????????????????????? break;
????????????????????? //中間的數據包類的類型省略
????????????????????? ? 。。。
??????????????????????? case "Status":
??????????????????????????? sdp.Status = Convert.ToByte(str2[1]);
??????????????????????????? break;
??????????????????????? case "Tail":
??????????????????????????? sdp.Tail = Convert.ToByte(Convert.ToInt16(str2[1]));
??????????????????????????? break;
??????????????????? }
??????????????? }
??????????????? return sdp;
??????????? }
??????????? catch (Exception ex)
??????????? {
??????????????? throw ex;
??????????? }
??????? }
