如何正确使用.NET串口.BaseStream进行异步操作

using System;
using System.IO.Ports;

class Program
{
    static void Main(string[] args)
    {
        SerialPort serialPort = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);
        serialPort.Open();

        byte[] buffer = new byte[1024];
        serialPort.BaseStream.BeginRead(buffer, 0, buffer.Length, new AsyncCallback(ReadCallback), serialPort);

        Console.ReadLine();
    }

    static void ReadCallback(IAsyncResult ar)
    {
        SerialPort serialPort = (SerialPort)ar.AsyncState;
        int bytesRead = serialPort.BaseStream.EndRead(ar);

        if (bytesRead > 0)
        {
            byte[] data = new byte[bytesRead];
            Array.Copy(buffer, data, bytesRead);

            // 处理读取的数据
        }

        // 继续异步读取
        byte[] buffer = new byte[1024];
        serialPort.BaseStream.BeginRead(buffer, 0, buffer.Length, new AsyncCallback(ReadCallback), serialPort);
    }
}
