C#3.0串口接口实现类

//用于线程同步，初始状态设为非终止状态，使用手动重置方式 private EventWaitHandle allDone = new EventWaitHandle(false, EventResetMode.AutoReset); SerialPort _serialPort = new SerialPort(); //声明获取时间委托 public delegate void EventHandlerDataReceived(byte[] param); //获取数据事件 public EventHandlerDataReceived DataReceived; //声明获取事件委托 public delegate void EventHandlerStatusChanged(string param); //获取事件信息 public EventHandlerStatusChanged StatusChanged; //串口号 public string PortName = "COM1"; //波特率 public int BautRate = 19200; //效验位 public Parity Parity = System.IO.Ports.Parity.None; //数据位 public int DataBits = 8; //停止位 public StopBits StopBits = System.IO.Ports.StopBits.One; //读写时间超时 public int ReadTimeout = 50; public int WriteTimeout = 50;
