Rewrite serial port communicationf rom C++ to C# -

i want know if correctly mapped c++ code establishes serial port communication c#.

void func(...) {  *hdev = createfile(portnameunc, generic_read|generic_write, 0, null,        open_existing, file_attribute_normal, null);      if(*hdev == invalid_handle_value) return false ;      dcb *dcb = new dcb ;     memset(dcb, 0x00, sizeof(dcb)) ;     dcb->dcblength       = sizeof(dcb);     dcb->baudrate        = baudrate;     dcb->parity          = parity;     dcb->stopbits        = stopbits;     dcb->bytesize        = bytesize;     dcb->fbinary         = true;     dcb->fdsrsensitivity = 0;     dcb->fdtrcontrol     = (dtr ? dtr_control_enable : dtr_control_disable) ;     dcb->frtscontrol     = (rts ? rts_control_enable : rts_control_disable) ;     dcb->foutxctsflow    = (cts ? 1 : 0) ;     dcb->foutxdsrflow    = (dsr ? 1 : 0) ;     dcb->foutx           = (xonnxoff ? 1 : 0) ;     dcb->finx            = 0 ;            if(!setcommstate(*hdev, dcb))      {       delete dcb ;       closehandle(*hdev) ;       *hdev = invalid_handle_value ;       return false;     }       if(!settimeout(readtimeout, readintervaltimeout) || !reset())        {          closehandle(*hdev) ;       *hdev = invalid_handle_value ;       return false;     } }  bool serial::settimeout(dword readtimeout, dword readintervaltimeout) {   commtimeouts *timeouts = new commtimeouts ;   memset(timeouts, 0, sizeof(commtimeouts)) ;   timeouts->readintervaltimeout          = readintervaltimeout ;   timeouts->readtotaltimeoutmultiplier   = 5 ;   timeouts->readtotaltimeoutconstant     = readtimeout ; //...   timeouts->writetotaltimeoutconstant    = 0 ; //   timeouts->writetotaltimeoutmultiplier  = 2*baudrate/8 ;   const bool ret = setcommtimeouts(*hdev, timeouts) != false ;   delete timeouts ;   m_currenttimeout = readtimeout ;   return ret ; } 

this c# mapping:

 public serialporthasp(string portname, int baudrate, parity parity, int databits, stopbits stopbits, bool dtr, bool rts, bool xonxoff)         {              m_port = new serialport(portname, baudrate, parity, databits, stopbits);              // store parameters user entered             m_portname = portname;             m_baudrate = baudrate;             m_parity = parity;             m_databits = databits;             m_stopbits = stopbits;             m_xonxoff = xonxoff;             m_dtr = dtr;             m_rts = rts;              // set xonxoff if set             if (xonxoff)                 m_port.handshake = handshake.xonxoff;              // set dtr/rts             m_port.dtrenable = dtr;             m_port.rtsenable = rts;              m_port.readtimeout = 500; // or other values             m_port.writetimeout = 500;              // open port communications             m_port.open();         } 

i need implement other read write operations (according protocol) till can test if mapping right, why want double check if took correct approach in mapping above code c#? or should take this route pinvoke calls? or still try current approach?

ps. thing can see way can't replicate parameters c++ calls allow 1 make

i add initialization:

m_port.datareceived += _serial_datareceived; 

the event obtain data port. need async working.

and

void _serial_datareceived(object sender, serialdatareceivedeventargs e)  {    int _len = _serial.bytestoread;    byte[] _out = new byte[_len];    _serial.read(_out, 0, _len);  }
