Sending a file to a dynamic port using TCP

Question

I work with an application that receives a file using TCP protocol, the application processes the file and then sends it using the same protocol, I receive the file without problems, my problem is when I try to send the file, because I need to send the file to another The application that listens on the dynamic port, the code that I use to send these files is as follows:

internal void Send(byte[] buffer)
    {
        TcpClient _client = null;
        try
        {
            _client = new TcpClient(RemoteIPaddress, Dynamic_port);

            if (_client != null)
            {
                NetworkStream _clienttStream = _client.GetStream();
                _clienttStream.Write(buffer, 0, buffer.Length);
                _clienttStream.Flush();
                _clienttStream.Close();
                _clienttStream = null;
            }
        }
        catch 
        {
            if (_client != null)
            {
                _client.Close();
                _client = null;
            }
        }
    }

The question is, how can I send a file via TCP to a remote machine using a dynamic port
