如何在richTextBox中显示从串口接收到的数据啊？

Question

用SerialPort类监视串口，并接收数据，然后把它在richTextBox中显示
SerialPort类的用法很简单，狗狗或者msdn

Answer 1

System.IO.Ports.SerialPort port = new System.IO.Ports.SerialPort("COM5");//定义串口        private void Form1_Load(object sender, EventArgs e)
        {
            port.BaudRate = 19200;
            port.Open();
            port.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(port_DataReceived);//设置响应事件
            RichTextBox.CheckForIllegalCrossThreadCalls = false;//运行子线程修改RichTextBox的内容
        }        void port_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            int bytesToRead = port.BytesToRead;
            if (bytesToRead > 0)
            {
                char[] c = new char[bytesToRead];
                port.Read(c, 0, bytesToRead);
                richTextBox1.Text += new string(c);//显示串口出来的数据
            }
        }
