打开后表格破裂

Question

我不明白为什么无限长的开始时我的获胜表格会挂起。我怎样才能解决这个问题？当似乎没有任何工作时。我曾尝试通过事件进行操作，但是没有调用，但是我“从不同于创建它的线程访问”。我不知道我还能尝试什么，因为我试图将UI与逻辑分离。

 public GroupChatForm(string username)
        {
            gchat = new GroupChat(username);
            InitializeComponent();
        }

        private void GroupChat_Load(object sender, EventArgs e)
        {
            listMessage.Text = gchat.Start();
            Thread ctThread = new Thread(postMessage);
            ctThread.Start();
        }
        private void postMessage()
        {
            while (true)
            {
                if (this.InvokeRequired)
                    this.Invoke(new Action(postMessage));
                else //listMessage.BeginInvoke(new Action(() => listMessage.Text = listMessage.Text + gchat.getMessage()));
                    listMessage.Text = listMessage.Text + gchat.getMessage();
            }
        }

不确定您尝试过什么...这里是我在说的“简化”版本：

public class GroupChatForm : Form
{

    public void foo()
    {
        GroupChat gc = new GroupChat();
        gc.MessageReceived += Gc_MessageReceived; // wire up the event
        gc.Start();
    }

    private void Gc_MessageReceived(string message)
    {
        if (this.InvokeRequired)
        {
            this.Invoke(new MethodInvoker(delegate
            {
                Gc_MessageReceived(message); // recursive call that will become UI safe on the second call
            }));
        }
        else
        {

            // ... it's safe to update your GUI in here with "message" ...

        }
    }

}

public class GroupChat
{

    public delegate void dlgMessage(String message);
    public event dlgMessage MessageReceived;

    public void Start()
    {
        // setup your TCP stuff
        // start a new thread that has MessageLoop() below in it
    }

    public void MessageLoop() // ... running in a new THREAD ...
    {
        String message;
        bool newMessageReceived = false;
        while (true)
        {

            // ... blocking code that receives a message ...

            message = "some message from the stream";
            newMessageReceived = true;

            if (newMessageReceived)
            {
                // raise the event w/ the message
                MessageReceived?.Invoke(message);
                newMessageReceived = false;
            }
        }

    }

}
