Aam trying to populate list of available ports in my system.
Following is my code which works in windows xp, but does not work in windows 7

public void loadPorts()
        {
            try
            {
                ManagementObjectSearcher searcher =
                    new ManagementObjectSearcher("root\\CIMV2",
                    "SELECT * FROM Win32_PnPEntity");

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    if (queryObj["Caption"].ToString().Contains("(COM"))
                    {
                        cmbPort.Items.Add(queryObj["Caption"]);
                    }

                }
            }
            catch (ManagementException e)
            {

        }

What is the desired behaviour?
What does actually happen?
Is there an error message?
What line does yields the error?

Solution 1

Try:

C#

string[] ports = SerialPort.GetPortNames();
foreach (string p in ports)
    {
    Console.WriteLine(p);
    }
