Serial Port Question with more sense

Hi All,
I tried to ask the question but was at the end of a Caffine fueled programming marathon, possibly not making sense, raging at the customer etc. The issue I have is I need to use a method like

C#

cboPorts.DataSource = SerialPort.GetPortNames;

How ever the app errors if it is opened on a PC with no Com Ports, it was hard to find this error as nearly every PC has a Serial Port and it was only possible to isolate it with a PC that only had USB com ports and these were removed before run it seems I need to check for any Serial Ports before I do any thing else.
I was doing the following after I had found the serial Ports

C#

do
{
  index += 1;
  cboPort.Items.Add(nameArray[index]);
    }
while (!((nameArray[index]==myComPortName)||(index == nameArray.GetUpperBound(0))));

I have have just moved this so it is the first thing in the Form Load I am now going to test it!

Is this the right way is there a right way?

Solution 1

Why wouldn't you just do this:

string[] portNames = SerialPort.GetPortNames();
if(portNames.Length == 0)
    // No ports found.
else
    // Do your binding.
