Question

How would one design a class for server, which is managed by simple client messages, in a proper way? This server uses event model to inform parent application about client requests. It uses asynchronous sockets. Server load is probably very limited.

This is what I would try:

class Client
{
private Socket sock;

public event EventHandler Start;
public event EventHandler Stop;
public event RequestEventHandler Request;

public Client(TcpClient Client)
//sock.BeginReceive

private void OnReceived(IAsyncResult ar)
//Dissect incoming stream into messages
//Call event handlers
//sock.BeginReceive

public void AnswerRequest(byte[] answer) //either this way or
private void OnSend(IAsyncResult ar)     //direct call of sock.BeginSend
}

class Server
{
private TcpListener Listener;
public List<Client> Clients;

public event EventHandler ClientConnected;

public Server(int port)
//Listener.BeginAcceptTcpClient

private void AcceptTcpClientCallback(IAsyncResult ar)
//Get TcpClient
//Create new Client with TcpClient as a parameter
//Launch ClientConnected, where one should sign for Client events
//Listener.BeginAcceptTcpClient
}

i’m using nito async library, it has simpleserversocket and simple client.
very easy to use.
