1 solution

Add the following directives to your project:
C#
using System.IO;
using System.IO.Ports;


Use a function similar to this to retreive a list the available ports.
C#
public string[] findPorts()
{
    // Creates and returns a string array with port names.
    string[] foundPorts = SerialPort.GetPortNames();
    return foundPorts;
}
