❔ Receive data from tcp client by one

Hello, the code is below, the problem is that the data is wrote only when the client disconnects, which is not correct

            TcpListener listener = new(8080);
            listener.Start();
            while (true)
            {
                Debug.WriteLine("Waiting for client...");

                // Accept an incoming client connection
                TcpClient client = await listener.AcceptTcpClientAsync();
                Debug.WriteLine("Client connected!");
                NetworkStream stream = client.GetStream();
                StreamReader reader = new StreamReader(stream, Encoding.UTF8);

                // Read data from the client
                while (client.Connected)
                {
                    string? data = await reader.ReadLineAsync();
                    if (data == null) break;
                    Debug.WriteLine("Received data: " + data);
                }
                client.Close();
                Debug.WriteLine("Client disconnected.");
            }

            TcpListener listener = new(8080);
            listener.Start();
            while (true)
            {
                Debug.WriteLine("Waiting for client...");

                // Accept an incoming client connection
                TcpClient client = await listener.AcceptTcpClientAsync();
                Debug.WriteLine("Client connected!");
                NetworkStream stream = client.GetStream();
                StreamReader reader = new StreamReader(stream, Encoding.UTF8);

                // Read data from the client
                while (client.Connected)
                {
                    string? data = await reader.ReadLineAsync();
                    if (data == null) break;
                    Debug.WriteLine("Received data: " + data);
                }
                client.Close();
                Debug.WriteLine("Client disconnected.");
            }

i would say while (client.Connected) is not really needed you can just loop on data == null apart from that, are you sure the issue is not in the client?

JakenVeina•15mo ago

definitely gonna need a better explanation of the issue

nvm, i found out i dont need to use tcp stuff, i just need to use unixdomain sockets...

Koblížkáč•15mo ago

but i dont get what am i doing wrong

boiled goose•15mo ago

you had problems using the simple high level stuff and you want to go down the abstraction layer? sorry but it doesn't seem the right thing to do (yet)

Koblížkáč•15mo ago

aight, im gonna do more research about it then

boiled goose•15mo ago

doing a simple socket console between two processes is easy, i even did with a one liner once that's why it's weird that there are errors, and in the code i saw it doesn't seem like there aren't any so maybe the problem isn't there

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
