c# - How do you read the serial port with windows 10 core -

using python on raspberry pi use similar code shown below read data serial port:

baud = 9600                 # baud rate port = '/dev/ttyacm0'       # serial urf port on computer  ser = serial.serial(port, baud) ser.timeout = 0  var message = ser.read(9); 

essentially want able read message off serial port , perform action based on message.

how can achieved using windows 10 core , c#, can point me in right direction or provide code sample?

thanks in advance received.

it turns out serial port on pi not supported yet, frustrating: https://www.raspberrypi.org/forums/viewtopic.php?t=109047&p=751638

here supported way:

serialport = await serialdevice.fromidasync(comportid);  serialport.writetimeout = timespan.frommilliseconds(1000);   serialport.readtimeout = timespan.frommilliseconds(1000);   serialport.baudrate = 115200;  serialport.parity = serialparity.none;   serialport.stopbits = serialstopbitcount.one;   serialport.databits = 7;   serialport.handshake = serialhandshake.none;   serialport.isrequesttosendenabled = true;   datareaderobject = new datareader(serialport.inputstream);    // set inputstreamoptions complete asynchronous read operation when 1 or more bytes available datareaderobject.inputstreamoptions = inputstreamoptions.partial;  // create task object wait data on serialport.inputstream loadasynctask = datareaderobject.loadasync(readbufferlength).astask(cancellationtoken);  // launch task , wait             uint32 bytesread = await loadasynctask;             if (bytesread > 0)             {                 try                 {                     var msg = datareaderobject.readstring(bytesread);                 }                 catch (exception ex ) {                 } }
