C# SerialPort.close() bug解决方法

　　最近小了个串口小程序 ,发现在调用 close()方法关闭串口时,程序被挂起.查找了网络资料,网上说这是C#的一个bug.

摸索了半天,结合前人的程序整理出来一段代码,与大家分享.程序只有接收的部分.

namespace SerialPort_Controls
{
    public partial class Form1 : Form
    {
        //该程序可实现 ,串口数据的获取(读取新的一行)  波特率4800 串口1
        string data;
        private delegate void SetTextCallback(string text);
        Thread threadReceive;
        bool TestOff = true;
        public Form1()
        {
            InitializeComponent();
        }

        private void SynReceiveData(object serialPortobj)
        {          
             //   this.Text = "正在通信!";
            while (true)
            {
                data = serialPort1.ReadLine();
                SetText(data);
            }
        }
        private void button2_Click(object sender, EventArgs e)

                    threadReceive.Abort();
                    serialPort1.Close();//关闭端口
                    this.Text = "通信关闭";
                }     
        }
        private void SetText(string text)
        {

            // 如果它们不相同则返回true

                this.Invoke(d, new object[] { text });
            }
            else
            {
                this.textBox1.Text += text;
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                serialPort1.Open();
                //同步阻塞接收数据线程
                threadReceive = new Thread(new ParameterizedThreadStart(SynReceiveData));
                threadReceive.Start(serialPort1);
                TestOff = false;
                this.Text = "正在通信";            
            }
            catch (Exception ex)
            {
                MessageBox.Show("打开失败"+ex.Message);
            }
        }            
    }
