问题描述
我知道如何列出可用的串行端口,但是每次连接我的 Arduino 时,我如何才能找到正确的 COM 端口?COM 端口应该像 MessageBox.Show(COMport);
I know how to list the available Serial Ports but whow can I find the right COM port everytime I connect my Arduino? COM Port should be printed like MessageBox.Show(COMport);
我想在 Visual C# 应用程序中读/写 Arduino 数据.
I want to read/write Arduino data in a Visual C# application.

推荐答案
打开设备管理器,展开端口(COM & LPT)".插入 Arduino USB 连接,一个新的 COM 端口出现,名称为 Arduino UNO (COMxx).这是在我的机器上,因为我有一个 Arduino UNO.
Open Device manager, expand "Ports (COM & LPT)". Plug in the Arduino USB connection, a new COM port shows up with name Arduino UNO (COMxx). This is on my machine as I have an Arduino UNO.
您可以使用 WMI(Windows 管理规范)找到此字符串.我在一个类中使用下面的方法,并将 COMports 作为公共列表
You can find this string using WMI (Windows Management Instrumentation). I am using the method below in a class, and has COMports as a public List
using System;
using System.Collections.Generic;
using System.Linq;
using System.Management;
using System.Text;
using System.Windows;
public void getCOMportsValues()
{
try
{
if (COMports.Count > 0) COMports.Clear(); // COMports is a List<string>
ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_PnPEntity");
foreach (ManagementObject queryObj in searcher.Get())
{
string s = queryObj["Name"] as string;
if (s.Contains("(COM"))
COMports.Add(s);
}
}
catch (ManagementException e)
{
MessageBox.Show("An error occurred while querying WMI data: " + e.Message);
}
}
