How to send and receive object type

[Anonymous]

Hello，Object type cannot send and receive?

Heya a77a77a777,

You cannot receive a generic object type. It is impossible to determine what should happen with incoming byte[] if the final object type is unknown. This is not a limitation of NetworkComms.Net, rather a limitation of converting objects to byte[] in order to be sent over a network.

Hello, I use byte[] to receive, unable to deserialize

The sending end：

string mgs = Console.ReadLine();
User uu = new User()
{
Id = 1,
Name = mgs
};
MemoryStream stream = new MemoryStream();
IFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, uu);
stream.Flush();
byte[] theBytes = stream.ToArray();
stream.Close();
Console.WriteLine(NetworkComms.SendReceiveObject<byte[], string>(“Message”, “127.0.0.1”, 6003, “hehe”, 1000, theBytes));
Console.ReadLine();

The receiving end：

NetworkComms.AppendGlobalIncomingPacketHandler<byte[]>(“Message”, (header, connection, message) =>
{
IFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream(message);
User t = formatter.Deserialize(stream) as User;
stream.Close();
connection.SendObject(“hehe”, t.Name);
});
Connection.StartListening(ConnectionType.TCP,new IPEndPoint(IPAddress.Parse(“127.0.0.1”),6003));
Console.ReadKey(true);

Please see our tutorial on sending custom object type https://networkcomms.net/custom-objects/, if the client and server are both NetworkComms.Net you should not be doing this:

IFormatter formatter = new BinaryFormatter();
MemoryStream stream = new MemoryStream(message);
User t = formatter.Deserialize(stream) as User;
stream.Close();

Thank you for your reply，The key is the receiving end can not know the sending end to send what type of data to come over, I’ve seen your help document, your type is known, and I received end is not fixed

My aim is to become a universal receiver

An object is sent over a network as an array of bytes, e.g:

115
100
103
100
52

It is impossible to know what these bytes mean unless the correct type is known. For example:

int integer = BitConverter.ToInt32(result, 0);
//integer = 1684497523

string str = Encoding.ASCII.GetString(result);
//str = sdgd4

float dbl = BitConverter.ToSingle(result, 0);
//dbl = 1.7073744E+22

Which is the correct answer?
