C# 操作串口提示错误：由于IO线程退出或应用程序请求，已中止IO操作。

Question

贴出代码
1.线程循环发送
public void PortListenThread()
{
while (true)
{
byte[] query = new byte[8] { 0x01, 0x02, 0x00, 0x00, 0x00, 0x10, 0x79, 0xC6 };
serPort.DiscardInBuffer();
serPort.Write(query, 0, query.Length);
Delay(500);
}
}

2.一个字节自动触发接收
public void IO_EventHandler(object sender, SerialDataReceivedEventArgs e)
{
int count = 0;

        Delay(100);

        count = serPort.BytesToRead;

        if (count < 6)
        {
            serPort.DiscardInBuffer();
        }
        else if (count > 6)
        {
            byte[] readBuffer = new byte[count];

            try
            {
                serPort.Read(readBuffer, 0, count);//报错：由于IO线程退出或应用程序请求，已中止IO操作。
            }
            catch (Exception a)
            {
                MessageBox.Show(a.Message);
            }

Answer 1

启动PortListenThread时，改用新线程。
如:
new Thread(PortListenThread).Start();
