Question

I implemented a Client and Server model that uses Socket with thread

When I want to pass only a string from Client to the Server, it works. But I want to pass an object and it throws this error:
“Attempting to deserialize an empty stream”

Here is the code:

---

Client:

ASCIIEncoding asen = new ASCIIEncoding();

MemoryStream memoryStream = new MemoryStream();
BinaryFormatter binaryFormatter = new BinaryFormatter();
Command command = new Command("meuLogin", "minhaSenha");
binaryFormatter.Serialize(memoryStream, command);

stream.Write(memoryStream.ToArray(), 0, memoryStream.ToArray().Length);

---

Server:

byte[] message = new byte[4096];
int bytesRead = 0;
bytesRead = clientStream.Read(message, 0, 4096);

MemoryStream memoryStream = new MemoryStream(bytesRead);
BinaryFormatter bf1 = new BinaryFormatter();
memoryStream.Position = 0;

Command command = (Command)bf1.Deserialize(memoryStream); 

---

Another question: I copied the class Command from Client and pasted at Server to deserialize. Is this correct?

Thank you

I also recommend WCF. But if you continue using sockets, the key element that you’re missing in your protocol is message framing.
