Hi I use this code for getting available com ports from computer with C#
string ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
comboBox1.Items.Add(port);
}
My question is that How can I get only Arduino port because I get all ports and I take exception on my desktop program. I want to take only arduino ports.
Anybody have idea?
I Found 
here is code
try
{
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(“root\CIMV2”,
“SELECT * FROM Win32_PnPEntity”);
foreach (ManagementObject queryObj in searcher.Get())
{
if (queryObj[“Caption”].ToString().Contains(“Arduino”))
{
Console.WriteLine(queryObj[“Caption”]);
}
}
Console.ReadLine();
}
catch (ManagementException e)
{
Console.WriteLine(e.Message);
}
dont forget add reference System.Management
