What is the method of serial communication in WinForms?

There are multiple ways to perform serial communication in WinForms applications, and here are two commonly used methods:

1. Utilize the SerialPort class provided by the .NET Framework: The SerialPort class is a class used for serial communication in the .NET Framework, located in the System.IO.Ports namespace. This class can be used to perform operations such as opening, closing, reading, and writing serial port data. Here is a simple example of using the SerialPort class:

using System.IO.Ports;

// 创建SerialPort对象
SerialPort serialPort = new SerialPort();

// 设置串口参数
serialPort.PortName = "COM1";
serialPort.BaudRate = 9600;
serialPort.Parity = Parity.None;
serialPort.DataBits = 8;
serialPort.StopBits = StopBits.One;

// 打开串口
serialPort.Open();

// 发送数据
serialPort.Write("Hello, World!");

// 接收数据
string receivedData = serialPort.ReadExisting();

// 关闭串口
serialPort.Close();

1. Utilize third-party libraries, such as EasySerial: EasySerial is an open-source serial communication library that simplifies serial communication operations. You can add EasySerial to your project using NuGet package manager. Here is a simple example of using EasySerial:

using EasySerial;

// 创建SerialPortManager对象
SerialPortManager serialPortManager = new SerialPortManager();

// 打开串口
serialPortManager.OpenPort("COM1", 9600);

// 发送数据
serialPortManager.Write("Hello, World!");

// 接收数据
string receivedData = serialPortManager.Read();

// 关闭串口
serialPortManager.ClosePort();

Both methods can achieve serial communication, the choice between them depends on individual needs and preferences.
