How to Populate a Combo-Box with Serial Port Descriptions Using WMI?

Populating Combo-Box with Serial Port Descriptions

Obtaining the descriptions of serial ports for display in a combo-box can be achieved using management objects and LINQ. A code snippet can be used to enumerate the serial ports and retrieve their descriptions:

<code class="csharp">using System.Linq;
using System.Management;

var managementSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE Caption like '%(COM%'");
var portnames = SerialPort.GetPortNames();
var ports = managementSearcher.Get().Cast<ManagementBaseObject>().ToList().Select(port => port["Caption"].ToString());

var portList = portnames.Select(portname => portname + " - " + ports.FirstOrDefault(portDesc => portDesc.Contains(portname))).ToList();</code>

This code enumerates the available serial port names using SerialPort.GetPortNames() and retrieves the corresponding port descriptions using WMI. It then combines the port names and descriptions into a single list, which can be used to populate a combo-box with both the port names and their descriptions.
