How to Retrieve Serial Port Details and Descriptions with WMI?

Retrieving Serial Port Details

Your question pertains to enriching a combo-box with serial port information, including their descriptions as displayed in Device Manager. To achieve this, you'll need to employ WMI (Windows Management Instrumentation) to delve deeper into the system's hardware details.

Here's an enhanced solution:

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

    var portList = portnames.Select(n => n + " - " + ports.FirstOrDefault(s => s.Contains(n))).ToList();

    foreach (string s in portList)
    {
        Console.WriteLine(s);
    }
}

This updated code utilizes WMI to retrieve the "Caption" property, which represents the human-readable description of the serial port. By combining the port name and description, it provides a more comprehensive view of each port. Additionally, the sorting issue has been addressed within your provided code snippet.
