>> We can get the COM port list available in the local system using the Name space System.Management.

>> The Serial port class's GetPortNames() method is used to get the COM Ports alone.
Eg.

String[] COMS =System.IO.Ports.SerialPort.GetPortNames();

>> We need to list the all the Ports available in the Local System then the ManagementObjectSearcher Class used.
Eg.

    ManagementObjectSearcher ObjUsbSearcher = new ManagementObjectSearcher("Select * from WIN32_SerialPort");

>> The bellow code is Navigate through the ObjUsbSearcher

foreach(ManagementObject Port1 in ObjUsbSearcher.Get())
            {
                listBox1.Items.Add((String)Port1.GetPropertyValue("Name"));
                
            }
