void DataReceived(ProtocolSocket socket, object service, NotifyDataChangedEventArgs e) {
    var io   = (IPacketIOService)service;    // TcpServer uses IPacketIOService.
    var args = (PacketChangedEventArgs)e;    // IPacketIOService posts PacketChangedEventArgs when it raises a DataChanged event.

    // With the packet that was received.
    using (var packet = args.GetPacket()) {
        var message = packet.ReadString();   // Read the message and log it.

    }

    // Send back a reply.
    using (var packet = io.Write()) {
        packet.WriteString("hello");         // The message is the string "hello".
