Finding/Listing usb/bluetooth/... serial-ports with System.Manageme nt.dll[reposted from microsoft.publi c.dotnet.framew ork.sdk, microsoft.publi c.dotnet.framew ork.wmi]

[Helge Jensen]

Having posted in microsoft.publi c.dotnet.framew ork.sdk and
microsoft.publi c.dotnet.framew ork.wmi without receiving any response, I
posthere on the off-chance that someone who isn't following those groups
knows a solution.

I'm using code (roughly like):

using System;
using System.Manageme nt;
public class Foo {
public static void Main() {
foreach ( ManagementObjec t port
in new ManagementClass ("Win32_SerialP ort").GetInstan ces() )
Console.WriteLi ne("{0}: {1}", port["deviceid"], port["name"]);
}
}

To query for the serial ports present on a system.

Unfortunatly, this doesn't seem to include COM-ports available via
usb-adapters or bluetooth. These devices are visible in the
DeviceManager in System->Hardware->DeviceManage r->Ports (COM & LPT), and
I want to get the same list as that, just without the LPT ports.

What am I doing wrong?

I had trouble finding info on the web, so here's something for the
search engines to catch on for the benefit of the next guy.

Keywords: com, com-port, serial-port, WMI, System.Manageme nt, .NET, C#,
enumerating, listing, finding, searching, win32, windows, win32api)
