Hey I'm a little blocked with .Net Framework implementation of B4XSerializator. I have a B4J Server communicates with my B4A apps all is good. But I want to send and recieve some data from the C#.NET client application that cannot be implemented to B4J for the moment. I send an object very well from the .Net App with this code.
And I recieve wit this code.
Now when I try sending the same Object to the C# application I can not get the object back. This is the code.
I have been struggling for nearly a week with this issue. I want to get the dictionary I sent back to me. I've tried all many code and I'm confused now.
This is the latest code.
What is wrong with these code ? Please help me solve. I saw this post with same problem but don't understand the solution at this level.
Is StreamExtensions a custom class or .Net Class ?
C#:
Dictionary<object, object> Dict = new Dictionary<object, object>();
Dict.Add("id", "HELLO1");
Dict.Add("msg", "MESSAGE1");
Dict.Add("senderid", "HELLO SENDER");
Dict.Add("receiverid", "ROOM1");
B4XType B4XMessage = new B4XType("Message", Dict);
B4XSerializator B4XSer = new B4XSerializator();
//---create a TCPClient object at the IP and port no.---
TcpClient client = new TcpClient(SERVER_IP, PORT_NO);
NetworkStream nwStream = client.GetStream();
byte[] bytesToSend = B4XSer.ConvertObjectToBytes(B4XMessage);
int BufferLen = bytesToSend.Length;
byte[] Prefix = BitConverter.GetBytes(BufferLen);
// ---send the text---
if (nwStream.CanWrite)
{
nwStream.Write(Prefix, 0, Prefix.Length);
nwStream.Write(bytesToSend, 0, bytesToSend.Length);
nwStream.Flush();
}And I recieve wit this code.
B4X:
Type Message (id As String , senderid As String , receiverid As String , msg As String )
Dim receivedObject As Object = Serializator.ConvertBytesToObject(Buffer)
If receivedObject Is Message Then
Log(receivedObject)
End ifNow when I try sending the same Object to the C# application I can not get the object back. This is the code.
B4X:
Dim Message1 As Message
Message1.Initialize
Message1.id = 1
Message1.receiverid = "Hello World"
Message1.senderid = "Hello Tense"
Message1.msg = "Message"
Dim RCreateRemoteMessage() As Byte = Serializator.ConvertObjectToBytes(Message1)
SendCommand(RCreateRemoteMessage,Ast)I have been struggling for nearly a week with this issue. I want to get the dictionary I sent back to me. I've tried all many code and I'm confused now.

C#:
StreamExtensions.ToByteArray(result)
