如何捕获DataReceivedEventHandler抛出的异常？

using System;
using System.IO.Ports;

public class SerialPortExample
{
    private SerialPort _serialPort;

    public SerialPortExample()
    {
        _serialPort = new SerialPort("COM1", 9600);
        _serialPort.DataReceived += SerialPort_DataReceived;
    }

    private void SerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        try
        {
            // 尝试读取数据
            string data = _serialPort.ReadExisting();
            Console.WriteLine("Received data: " + data);
        }
        catch (Exception ex)
        {
            // 捕获并处理异常
            Console.WriteLine("An error occurred while reading data: " + ex.Message);
            // 可以在这里添加更多的异常处理逻辑，如记录日志、通知用户等
        }
    }

    public void OpenPort()
    {
        if (!_serialPort.IsOpen)
        {
            _serialPort.Open();
        }
    }

    public void ClosePort()
    {
        if (_serialPort.IsOpen)
        {
            _serialPort.Close();
        }
    }
}
