SerialPort + BeginInvoke实现串通信的多线程问题，高手请帮忙

Question

我想用SerialPort + BeginInvoke实现 当SerialPort收到数据时，先调用AnalyzeAndRespond方法 分析数据包数据 并作出相应的反应，然后再调用UpdateTextBox2方法将收到的数据显示到TextBox控件中，我这里该怎么做呀？怎么总是窗口死掉呀？我考虑是多线程的问题，但是我很菜，不知道该怎么弄了，请各位高手指点

Answer 1

怎么总是窗口死掉呀
是应为发生了死锁~
再好好去检查一下！线程的编写！
既然是线程的问题：
那你去学习一下线程：

private void AnalyzeAndRespond(byte [] readBuffer)//数据包分析并相应
{
}
 private void UpdateTextBox2(string text) //更新窗口显示信息
{}请帮忙分析，指点一下，谢谢
