how work serial port in c#

hi
i start work with c# three week ago
i'm an electronic engineer and i want send some data from micro to pc
i want work with c# for data monitoring
how can we work with serial port in c#?
thank you

 

I've written a few apps using the System.IO.Ports.SerialPort library.

It's pretty straight forward.

Simply create an instance of System.IO.Ports.SerialPort,


example from MSDN:

// Create a new SerialPort object with default settings.
System.IO.Ports.SerialPort _serialPort = new SerialPort();

// Allow the user to set the appropriate properties.
_serialPort.PortName = SetPortName(_serialPort.PortName);
_serialPort.BaudRate = SetPortBaudRate(_serialPort.BaudRate);
_serialPort.Parity = SetPortParity(_serialPort.Parity);
_serialPort.DataBits = SetPortDataBits(_serialPort.DataBits);
_serialPort.StopBits = SetPortStopBits(_serialPort.StopBits);
_serialPort.Handshake = SetPortHandshake(_serialPort.Handshake);

// Set the read/write timeouts
_serialPort.ReadTimeout = 500;
_serialPort.WriteTimeout = 500;

_serialPort.Open();


when you want to write something to the port

_serialPort.Write(.....);

there's a few different ways to write, you can write a string, or a byte array.

when your done with the port,

_serialPort.Close();
