C# and Win32_PortConnector Class

Win32_PortConnector Class:

It represents physical connection port Like Parallel Port ECP/EPP, Serial Port XT/AT Compatible SCSI Port,MIDI Port, Joy Stick Port, Keyboard Port, Mouse Port.

See the structure of Win32_PortConnector Class

class Win32_PortConnector : CIM_PhysicalConnector
{
string Caption;
string ConnectorPinout;
uint16 ConnectorType[];
string CreationClassName;
string Description;
string ExternalReferenceDesignator;
datetime InstallDate;
string InternalReferenceDesignator;
string Manufacturer;
string Model;
string Name;
string OtherIdentifyingInfo;
string PartNumber;
uint16 PortType;
boolean PoweredOn;
string SerialNumber;
string SKU;
string Status;
string Tag;
string Version;
};

You can understand property easily by its name.

Example: Serial Number represents the serial number of particular.

Here we basically explain the type of Port using property PortType.

And it returns the value of type uint16.

So the return value and its meaning is given in following table:

Values	Meaning
0	None
1	Parallel Port XT/AT Compatible
2	Parallel Port PS/2
3	Parallel Port ECP
4	Parallel Port EPP
5	Parallel Port ECP/EPP
6	Serial Port XT/AT Compatible
7	Serial Port 16450 Compatible
8	Serial Port 16550 Compatible
9	Serial Port 16550A Compatible
10	SCSI Port
11	MIDI Port
12	Joy Stick Port
13	Keyboard Port
14	Mouse Port
15	SSA SCSI
16	USB
17	FireWire (IEEE P1394)
18	PCMCIA Type II
19	PCMCIA Type II
20	PCMCIA Type III
21	CardBus
22	Access Bus Port
23	SCSI II
24	SCSI Wide
25	PC-98
26	PC-98-Hireso
27	PC-H98
28	Video Port
29	Audio Port
30	Modem Port
31	Network Port
32	8251 Compatible
33	8251 FIFO Compatible

Here is your code:

       private void button1_Click(object sender, EventArgs e)
        {
            Dictionary<UInt16, string> dict = new Dictionary<ushort, string>();
            dict.Add(0,"None");
            dict.Add(1,"Parallel Port XT/AT Compatible");
            dict.Add(2,"Parallel Port PS/2");
            dict.Add(3,"Parallel Port ECP");
            dict.Add(4,"Parallel Port EPP");
            dict.Add(5,"Parallel Port ECP/EPP");
            dict.Add(6,"Serial Port XT/AT Compatible");
            dict.Add(7,"Serial Port 16450 Compatible");
            dict.Add(8,"Serial Port 16550 Compatible");
            dict.Add(9,"Serial Port 16550A Compatible");
            dict.Add(10,"SCSI Port");
            dict.Add(11,"MIDI Port");
            dict.Add(12,"Joy Stick Port");
            dict.Add(13,"Keyboard Port");
            dict.Add(14,"Mouse Port");
            dict.Add(15,"SSA SCSI ");
            dict.Add(16,"USB");
            dict.Add(17,"FireWire (IEEE P1394)");
            dict.Add(18,"PCMCIA Type II");
            dict.Add(19,"PCMCIA Type II");
            dict.Add(20,"PCMCIA Type III");
            dict.Add(21,"CardBus");
            dict.Add(22,"Access Bus Port");
            dict.Add(23,"SCSI II");
            dict.Add(24,"SCSI Wide");
            dict.Add(25,"PC-98");
            dict.Add(26,"PC-98-Hireso");
            dict.Add(27,"PC-H98");
            dict.Add(28,"Video Port");
            dict.Add(29,"Audio Port");
            dict.Add(30,"Modem Port");
            dict.Add(31,"Network Port");
            dict.Add(32,"8251 Compatible");
            dict.Add(33,"8251 FIFO Compatible");

            var mos = new ManagementObjectSearcher();
            mos.Query = new ObjectQuery("SELECT * FROM Win32_PortConnector");
            foreach (ManagementObject mo in mos.Get())
            {
 
                    listBox1.Items.Add(dict[Convert.ToUInt16(mo["PortType"])]);

            }

        }

Dictionary is used to give meaning to the result with some messages.

The output will be as:



From above you can easily find the available ports. You can see that there is 4 usb ports, 1 for keyboard, 1 for mouse and etc.

Hope you understand it.

Thank you.
