{
string[] ArryPort = System.IO.Ports.SerialPort.GetPortNames();//获取到本地的串口
comboBox1.Items.Clear();
for (int i = 0; i < ArryPort.Length; i++)
{
comboBox1.Items.Add(ArryPort[i]);
}
}
private void button2_Click(object sender, EventArgs e)//打开串口
{
if (button2.Text == "启用端口")
{
try
{
serialPort1.PortName = comboBox1.Text;
serialPort1.Open();
button2.Text = "关闭端口";
button2.BackColor = System.Drawing.Color.Red;
serialPort1.BaudRate = Convert.ToInt32(comboBox2.Text);
this.Width = 1074;//改变窗体大小
this.Height = 786;//改变窗体大小
tabPage1.Parent = tabControl1;//显示标签
}
catch
{
System.Media.SystemSounds.Beep.Play();
MessageBox.Show("端口打开失败", "错误");
