C#学习教程：C＃串口读取HEX数据分享

我正在编写一个C＃应用程序，同时从多个串行COM端口读取数据，以分析IPOD的数据通信。 发送的数据需要解释为HEX字节。 例如，

0xFF 0x55 0x01 0x00 0x04 0xC3 0xFF 0x55 &＃8230;

我希望能够阅读此内容并将其显示在富文本框中

0xFF 0x55 0x01 0x00 0x04 0xC3 0xFF 0x55 ... 

命令的开头包括一个标题（0xFF 0x55），其余的是命令+参数+校验和。

最好的方法是什么？

我目前有：

 private delegate void SetTextDeleg(string text); void sp_DataReceivedRx(object sender, SerialDataReceivedEventArgs e) { Thread.Sleep(500); try { string data = IPODRxPort.ReadExisting(); // Is this appropriate?? // Invokes the delegate on the UI thread, and sends the data that was received to the invoked method. // ---- The "si_DataReceived" method will be executed on the UI thread which allows populating of the textbox. this.BeginInvoke(new SetTextDeleg(si_DataReceivedRx), new object[] { data }); } catch { } } private void si_DataReceivedRx(string data) { int dataLength = data.Length*2; double numLines = dataLength / 16.0; for (int i = 0; i  

 SerialPort sp = (SerialPort) sender; // string s = sp.ReadExisting(); // labelSerialMessage.Invoke(this.showSerialPortDelegate, new object[] { s }); int length = sp.BytesToRead; byte[] buf = new byte[length]; sp.Read(buf, 0, length); System.Diagnostics.Debug.WriteLine("Received Data:" + buf); labelSerialMessage.Invoke(this.showSerialPortDelegate, new object[] { System.Text.Encoding.Default.GetString(buf, 0, buf.Length) });
