WriteAsync doesn't always send data to all connected clients

I am making an application that has a TCP client that listens for messages from a TCP server, then puts those messages in a queue, then sends all of the queued messages to the connected TCP clients of the server started. The application is working, but sometimes WriteAsync doesn't send the same amount of messages to all clients. Any ideas of what the issues is, and also what can I improve on in this code? https://hastebin.com/fejosepufi.csharp Thanks

Are you checking the logs for any errors?

Determinism•2y ago

There are no errors, if I step through it in debug, all of the messages are sent If I run it without breakpoints, the problem occurs

Cutter•2y ago

have you checked any receive errors?

Determinism•2y ago

Ah, it looks to be combining the messages

Any idea on how I could prevent that?

Cutter•2y ago

idk i havent read through your code properly site and read how you are sending and recieving

Determinism•2y ago

Still seems strange as some clients receive 3 messages if sent 3 and other only receives 2

  var bytesMessage = new byte[5000];
                        count = await stream.ReadAsync(bytesMessage, cancellationToken);
                        var bytesReceived = new byte[count + 300];
                        Buffer.BlockCopy(bytesMessage, 0, bytesReceived, 0, count + 40);

                        Log.Information($"Message size is {count}, bytes read is {bytesReceived.Length}");

  var bytesMessage = new byte[5000];
                        count = await stream.ReadAsync(bytesMessage, cancellationToken);
                        var bytesReceived = new byte[count + 300];
                        Buffer.BlockCopy(bytesMessage, 0, bytesReceived, 0, count + 40);

                        Log.Information($"Message size is {count}, bytes read is {bytesReceived.Length}");

is this not just adding the message into the same array? so you'd need to determine how big the message being sent is somehow

Determinism•2y ago

True, so I only read in a certain amount of bytes, then can cut it off

Cutter•2y ago

yea
