C# でシリアル ポートの説明を取得するにはどうすればよいですか?

<code class="c#">using Microsoft.Management;

...

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);
    }
}</code>
