例如，您能否尝试这样的事情，我想您想利用的是 方法
using System;
using System.IO.Ports;
class SerialPortProgram
{
// Create the serial port with basic settings
private SerialPort port = new SerialPort("COM1",
9600, Parity.None, 8, StopBits.One);
[STAThread]
static void Main(string[] args)
{
// Instatiate this
SerialPortProgram();
}
private static void SerialPortProgram()
{
Console.WriteLine("Incoming Data:");
// Attach a method to be called when there
// is data waiting in the port's buffer
port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);
// Begin communications
port.open();
// Enter an application loop to keep this thread alive
Console.ReadLine();
}
private void port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
// Show all the incoming data in the port's buffer
Console.WriteLine(port.ReadExisting());
}
}
还是您想根据自己想做的事来做，可以尝试一下
public class MySerialReader : IDisposable
{
private SerialPort serialPort;
private Queue<byte> recievedData = new Queue<byte>();
public MySerialReader()
{
serialPort = new SerialPort();
serialPort.open();
serialPort.DataReceived += serialPort_DataReceived;
}
void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
{
byte[] data = new byte[serialPort.BytesToRead];
serialPort.Read(data, 0, data.Length);
data.ToList().ForEach(b => recievedData.Enqueue(b));
processData();
}
void processData()
{
// Determine if we have a "packet" in the queue
if (recievedData.Count > 50)
{
var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
}
}
public void Dispose()
{
if (serialPort != null)
{
serialPort.Dispose();
}
}
