How to get a list of all available Com Ports in C# with asp.net 4

Question

How can I list all of the available com ports to my computer?

I have seen a few examples wiht .net 1.1 so I was wandering is there is not a more modern way to go about doing this?

I have my serialPort called serialPort

I got this code from msdn site:

// 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);
}

It give me the following error: The name "SerialPort" Does not exist in the current context

I have tried changing it to a small s, and I then get this error:

Member 'System.IO.Ports.SerialPort.GetPortNames()' cannot be accessed with an instance        reference; qualify it with a type name instead    

Solution

The name "SerialPort" Does not exist in the current context error means you don't have the required references and/or namespace imports set on your project/file.

'System.IO.Ports.SerialPort.GetPortNames()' cannot be accessed with an instance reference; qualify it with a type name instead means you are trying to call a static method on an object instance (which is, obviously, impossible).

You need to fully qualify namespaces in your method call:

string[] ports = System.IO.Ports.SerialPort.GetPortNames();

or add a using directive:

using System.IO.Ports;
.....
string[] ports = SerialPort.GetPortNames();
