❔ Sockets, SendTo is erroring

A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.

With my setup, the socket is connected in a different class but I am trying to send a message to that socket via its endpoint where I get an error, is that possible or do I have to use the socket class its self?

    public static async Task SendToEndPointAsync(IPEndPoint target, WebSocketOpcodes webSocketOpCode, WebSocketEvents? eventType = null, string? dataSerialized = null)
    {
        try
        {
            var socketMessage = new WebSocketMessage(webSocketOpCode, dataSerialized, eventType, null);

            string messageSerialized = JsonSerializer.Serialize(socketMessage);

            byte[] dataCompressed = Encoding.UTF8.GetBytes(messageSerialized); /

            await Listener.SendToAsync(dataCompressed, SocketFlags.None, target);
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }

    public static async Task SendToEndPointAsync(IPEndPoint target, WebSocketOpcodes webSocketOpCode, WebSocketEvents? eventType = null, string? dataSerialized = null)
    {
        try
        {
            var socketMessage = new WebSocketMessage(webSocketOpCode, dataSerialized, eventType, null);

            string messageSerialized = JsonSerializer.Serialize(socketMessage);

            byte[] dataCompressed = Encoding.UTF8.GetBytes(messageSerialized); /

            await Listener.SendToAsync(dataCompressed, SocketFlags.None, target);
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }

the socket is connected in a different class

the error says otherwise the socket is not connected what is Listener?

S-IERRAOP•15mo ago

Listener is the main socket listening to all connections Similar to TCP Listener also as far as I can tell the connection stays alive other wise I'd be getting an error let me check tho

JakenVeina•15mo ago

but what IS it?

S-IERRAOP•15mo ago

Acts as a server OH EWAIT Im sorry i'm tired as fuck

    public static readonly Socket Listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

    public static readonly Socket Listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

ignore the debug info and stuff

S-IERRAOP•15mo ago

but its connected just the way i send it isnt thru the Socket class its thru the server -> Ip Endpoint i could make it send via the actual client socket thats on the server just would be alot more annoying because i would have to redesign alot of stuff Tho I assume I can't just send out data from the server when the 2 sockets arent connected (even tho they are but the way im sending isnt connected ig)
