Answer 1

You could use the thread pool:

string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
    ThreadPool.QueueUserWorkItem(state =>
    {
        // This will execute in a new thread
    });
}

or create and start the threads manually:

string[] ports = SerialPort.GetPortNames();
foreach (string port in ports)
{
    new Thread(() => 
    {
        // This will execute in a new thread
    }).Start();
}
