If you show port tree in another tree then post your tree..

Ilkin Turk · Answer

Mister Ketan does port tree must be visible serately as on windows 7 or under another title.

Windows 10 also display Port tree. While there is not port tree you dont get port names in application. Try to Re - install serial port device driver.

Hi, Try this code : using System; using System.IO.Ports; namespace SerialPortExample { public class SerialPortExample { public static void Main() { // Get a list of serial port names. string[] ports = SerialPort.GetPortNames(); Console.WriteLine( "The following serial ports were found:" ); // Display each port name to the console. foreach(string port in ports) { Console.WriteLine(port); } Console.ReadLine(); } } } Reference : https://msdn.microsoft.com/en-us/library/system.io.ports.serialport.getportnames(v=vs.110).aspx Demo : https://dotnetfiddle.net/mDFtPZ
