串口中的起始位是哪个属性和方法

Question

各位，本人正在写一个调用硬件的程序，由于这个硬件涉及到起始位。上不百度找也找不到，msdn也找不到，
没办法，只有请教各位了，帮帮忙啊

Answer 1

起始位：
这个有设置么？只有数据位长度吧。起始位都是0
停止位：
StopBits

Answer 2

建议上MSDN参考一下 SerialPort类，你说的起始位应该是“数据位” DataBits 吧

Answer 3

    public class MeterSetup
    {
        public int Recold;
        public int DataBits;
        public int BufferSize;
        public string ComPort;
        public int BaudRate;
        public string Parity;
        public string StopBits;
    }
  private void Begin(MeterSetup mst)
        {
            if (SpReceive == null) SpReceive = new SerialPort();
            SpReceive.DataReceived += new SerialDataReceivedEventHandler(SpReceive_DataReceived);            SpReceive.ReceivedBytesThreshold = mst.Recold;      //接收多少数据后触发事件
            SpReceive.DataBits = mst.DataBits;
            SpReceive.ReadBufferSize = mst.BufferSize;
            SpReceive.PortName = mst.ComPort;
            SpReceive.BaudRate = mst.BaudRate;            switch (mst.Parity)
            {
                case "偶校验":
                    SpReceive.Parity = Parity.Even;
                    break;
                case "奇校验":

                    break;
            }            switch (mst.StopBits)

                    break;
                case "2":
                    SpReceive.StopBits = StopBits.Two;
                    break;
            }            try
            {
                SpReceive.Open();
                if (readBuffer == null) readBuffer = new byte[SpReceive.ReadBufferSize];
            }
            catch (Exception ex)
            {
                throw ex;
            }
