WaitCommEvent with Listener in C++ Winforms application

I'm trying to write winforms that reads data from Arduino board. CLR application does not permit threads, so I have to solve this problem with a listener. How can I trigger Listener when a data is available at the port, by using WaitCommEvent

My code is like example2 on this site

Use the DataReceived of your COM Port. User ReadLine method in your com port, example :

private:
    System::Void comPort1_DataReceived(System::Object ^sender, System::IO::Ports::SerialDataReceivedEventArgs ^e)
    {
        System^ data = comPort1->ReadLine();
        this->Invoke(gcnew EventHandler(processData));
    }

    System::Void processData(System::Object ^sender, System::EventArgs ^e)
    {
        // data receive
    }

Using .Net, read this tutorial : http://www.c-sharpcorner.com/uploadfile/eclipsed4utoo/communicating-with-serial-port-in-C-Sharp/.
