C# - 从串口缓冲区读取 [英] C# - readin from serial port buffer

问题描述

我正在尝试从 RS-232 端口读取数据.有没有人举例说明我如何从端口/缓冲区获取数据并确保我拥有所有数据，因为它可以是多行数据.

I am trying to read data from an RS-232 port. Does anyone have an example of how I get the data from the port/buffer and make sure that I have all the data as it can be multiline data.

我是不是简单的把它读成下面这样?

Do I simply read it as follows ?

string Rxstring = port.ReadLine();
Console.WriteLine(Rxstring);

推荐答案

试试这个:

using System.IO.Ports;
...

private SerialPort port = new SerialPort("COM1", 9600, Parity.None, 8, StopBits.One);

Console.WriteLine(port.ReadExisting());

详细信息请参见 Coad 的代码.
