如何在c＃中手动修改serialport portname和baudrate [英] how to modify serialport portname and baudrate manually in c#

问题描述

Hai，

我正在做一个串口读写项目。它工作正常，但现在我想通过组合框从我的Windows窗体修改我的串口名称和波特率。用户想要从组合框中选择端口名和波特率，那时我的seialport属性必须根据组合框值进行更改。

例如现在我的项目使用serialport portname COM3读取和写入数据，并通过设置读取波特率9600我的表单中的serialport控件的属性。现在我想通过选择portname作为串口名称想要更改的COM1并同时读取和写入数据来通过组合框更改属性...

请帮助...

谢谢提前....
