Naimish Makwana · Answer

To read data from a serial port in C#, you can use the System.IO.Ports namespace, which provides the SerialPort class. Here's a simple example of how you can read data from a serial port in C#: using System; using System.IO.Ports; class SerialPortReadout { static void Main() { // Create a new SerialPort object SerialPort serialPort = new SerialPort(); // Set the serial port settings (you need to adjust these based on your device) serialPort.PortName = "COM1"; serialPort.BaudRate = 9600; serialPort.Parity = Parity.None; serialPort.DataBits = 8; serialPort.StopBits = StopBits.One; try { // Open the serial port serialPort.Open(); // Subscribe to the DataReceived event to handle incoming data serialPort.DataReceived += SerialPort_DataReceived; Console.WriteLine("Press any key to exit."); Console.ReadKey(); } catch (Exception ex) { Console.WriteLine($"Error: {ex.Message}"); } finally { // Close the serial port when done if (serialPort.IsOpen) { serialPort.Close(); } } } private static void SerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e) { // This method will be called when data is received on the serial port SerialPort serialPort = (SerialPort)sender; // Read the available bytes from the serial port int bytesToRead = serialPort.BytesToRead; byte[] buffer = new byte[bytesToRead]; serialPort.Read(buffer, 0, bytesToRead); // Convert the byte array to a string (you may need to adjust the encoding) string receivedData = System.Text.Encoding.ASCII.GetString(buffer); // Display the received data Console.WriteLine($"Received data: {receivedData}"); } } Make sure to adjust the PortName , BaudRate , Parity , DataBits , and StopBits properties based on the settings of your serial device.
