How to get specifik name of comport?

[Askelassen]

Hello.

My question is as follows:

I am making a little gui that uses COMPORTS to connect to a board. I want the program to be able to find the correct COMPORT by itself. This goes fine with try/catch as long as I dont have other devices that uses COMPORTS. My code so far is as follows:

  public void InitSerialPort()
        {
 
            int i = 0;
            bool comportSelect = false;
 
            while (comportSelect == false)
            {
                try
                {
                    if (i == 21)
                    {
                        Error(0);
                        comportSelect = true;
                    }
                    else
                    {
                        mySerialPort = new SerialPort(("COM" + i.ToString()), 19200, Parity.None, 8, StopBits.Two);
                        mySerialPort.DataReceived += new SerialDataReceivedEventHandler(Received);
                        mySerialPort.Open();
                        mySerialPort.
                        MessageBox.Show(mySerialPort.PortName);
                        comportSelect = true;
                    }
                }
                catch
                {
                    i++;
                }
            }
        }

This doesn't work when I have an other device using a lower COMPORT as the one for my gui. If I open device manager I can see different desciptions of the comports. The one I want to use is described as:

"USB Serial Port (COM3)"

Do you guys know a way to return this description so I can do a "chec" to see wheater I have selected the right COMPORT?

Thanks allready!

There is a way to get some information about them using WMI (like in http://www.python-forum.org/pythonfo...t=7175&p=88622 )

I'm writing in c# in visual studio :) so can I use this?

How can I know? If there is a way to access WMI from c# (I'm sure there is) then yes, I permit you to use this for whatever purposes.
