C#serialport控件详细用法

首先是打开串口：
serialPort1.PortName = portList.SelectedItem.ToString();
serialPort1.BaudRate = Convert.ToInt32(baudrateList.SelectedItem.ToString());
serialPort1.StopBits = StopBits.One;
serialPort1.Parity = Parity.None;
serialPort1.DataBits = 8;
serialPort1.Handshake = Handshake.None;
this.serialPort1.DataReceived += new SerialDataReceivedEventHandler(serialPort1_DataReceived);
serialPort1.Open();

然后就是数据的接收了：
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
string readString = serialPort1.ReadExisting();
}

然后就自己组织一下吧，我只是截取了片段的代码。
