本文主要介绍了c# 使用线程对串口serialPort进行收发数据，分享给大家，具体如下：
一共写了四种方法，窗体界面都是一样的：
方法一：

}
private void Form1_Load(object sender, EventArgs e)
{
//检查是否含有串口
string[] str = SerialPort.GetPortNames();
for (int i = 0; i < str.Length; i++)
{
comboBox1.Items.Add(str[i]);
}
button2.Enabled = false;
button3.Enabled = false;
button4.Enabled = false;
dataGridView1.Rows.Add(68);
//标序号
for (int i = 0; i < 69; i++)
{
dataGridView1.Rows[i].Cells[0].Value = i;
}
