Open a tcp socket and continuously read the stream in a non-working way. Items in the stream are seperated by a cartridge return. Please use regex to remove the non numeric characters from the item but allow the decimal point.

    class Program
    {
        static void Main(string[] args)
        {
            var tcpClient = new TcpClient("localhost", 1234);
            var networkStream = tcpClient.GetStream();
            while (true)
            {
                while (!networkStream.DataAvailable) { }
                var buffer = new byte[tcpClient.ReceiveBufferSize];
                var bytesRead = networkStream.Read(buffer, 0, tcpClient.ReceiveBufferSize);
                var message = System.Text.Encoding.UTF8.GetString(buffer, 0, bytesRead);
                var cleanMessage = message.Split('\n')
                                          .Select(x => x.Split('\r')[0])
                                          .Where(x => Regex.IsMatch(x, @"^(\d+\.?)?\d*$"))
                                          .ToList();
                cleanMessage.ForEach(x => Console.WriteLine(x));
