C#串口初始化

           //通信端口

            string[] PortList = SerialPort.GetPortNames();

            if (PortList.Length > 0)

            {

                this.cmb_Port.DataSource = PortList;

                this.cmb_Port.SelectedIndex = 0;

            }

            //波特率

            string[] BaudList = new string[] { "2400", "4800", "9600", "19200", "38400" };

            this.cmb_Baud.DataSource = BaudList;

            this.cmb_Baud.SelectedIndex = 2;

            //校验位

            this.cmb_Parity.DataSource = Enum.GetNames(typeof(Parity));

            this.cmb_Parity.SelectedIndex = 0;

            //停止位

            this.cmb_StopBits.DataSource = Enum.GetNames(typeof(StopBits));

            this.cmb_StopBits.SelectedIndex = 1;

            //数据位

            int[] DataList = new int[] { 5, 6, 7, 8 };

            this.cmb_DataBits.DataSource = DataList;

            this.cmb_DataBits.SelectedIndex = 3;

            //校验方式

            this.cmb_ParityMethod.DataSource = Enum.GetNames(typeof(ParityMethod));

            this.cmb_ParityMethod.SelectedIndex = 0;

设置串口属性

            this.serialPort.PortName = this.cmb_Port.Text.Trim();

            this.serialPort.BaudRate = Convert.ToInt32(this.cmb_Baud.Text.Trim());

            this.serialPort.Parity = (Parity)Enum.Parse(typeof(Parity), this.cmb_Parity.Text.Trim(), true);

            this.serialPort.DataBits = Convert.ToInt32(this.cmb_DataBits.Text.Trim());

            this.serialPort.StopBits = (StopBits)Enum.Parse(typeof(StopBits), this.cmb_StopBits.Text.Trim(), true);
