POUniting TCP and UDP in C#
text
Body
copied!<p>So ideally, I am looking for a way to unite TCP and UDP on the server and manage both these connections under individual client threads. Currently, I am wondering if it is possible to accept a TCP connection and set up UDP communication from that.</p> <p>Here is my ideal setup:</p> <ol> <li>Client connects on TCP to server via TCPClient.connect()</li> <li>Server accepts TCP connection via TCPListener</li> <li>when server accepts TCP connection, it also gets the IPEndpoint from the TCP connection</li> </ol> <p>and uses that to begin UDP communcation with:</p> <pre><code>serverUDPSocket.BeginReceiveFrom (byteData, 0, 1024, SocketFlags.None, ref (Endpoint)ThatIPEndpointThatIJustMentioned, new AsyncCallback(client.receiveUDP), (Endpoint)ThatIPEndpointThatIJustMentioned); </code></pre> <p>^so this is where I am running into a little bit of a theoretical issue. From my understanding, the endpoints for TCP and UDP would be formatted differently. How can I resolve this issue? I would like to avoid having the client connect to UDP on a separate thread and then uniting these threads under a single managing class.</p> <p>EDIT:</p> <p>Here is the code that I am trying to implement:</p> <pre><code>//Listening for TCP TcpClient newclient = listenTCP.AcceptTcpClient(); //Accept the client Client clientr = new Client(newclient); //Create a new Client class to manage the connection clientr.actionThread = new Thread(clientr.action); //This thread manages the data flow from the client via the TCP stream clientr.actionThread.Start(clientr); EndPoint endPoint = newclient.Client.RemoteEndPoint; //so this is the sketchy part. I am trying to get the endpoint from the TCP connection to set up a UDP "connection". I am unsure about the compatibility as UDP and TCP sockets are different. UDPSocket.BeginReceiveFrom(new byte[1024],0,1024, SocketFlags.None,ref endPoint, new AsyncCallback(clientr.receiveUDP), null); //the AsyncCallBack is like the manager thread for UDP (same as in TCP) clients.Add(clientr); </code></pre>
