如何实时读取串口扫码枪数据

Question

private void serialPort_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e) {  this.serialPort.Read(byteMessage, 0, byteMessage.Length);        XXXXXXXXX();}

Answer 1

private void serialPort_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            Invoke(getDataHandler);
        }

Answer 2

serialPort自带了事件的，只要读到数据，就会触发DataReceived事件

Answer 3

用C#自带的串口控件或者串口类都可以实现，如上面几位所说的，它自带DataReceived接收事件这个辅助线程的
