使用Joson的格式字符串在Socket中通訊時數據格式的轉換

最近在測試通訊模塊時，發現新增的Android平台發送過來的數據，服務器端總是收不到，後來發現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後轉化為對象。同時在服務端進行發送數據時，轉換為Joson格式後，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;
}
