How to pass data from picker to email?

I'm new to Xamarin and i just can't wrap my head around the timepicker, datepicker or picker. I can get the functionality to work in the app i'm playing around with, but how do i pass that information to say an email all the other form entrys i have works well, just not the pickers.

i have this for time in xaml file:

<Picker.Items>

RSW-Southwest Florida
MIA-Miami
FLL-For Lauderdale
APF-Naples
TPA-Tampa
MRK-Marco Island
MCO-Orlando
PBI-West Palm Beach
SRQ-Sarasota-Bradenton
Port of Miami
Port Everglades
</Picker.Items>

i need to be able to pass that information selected to an email

here is the CS file

{
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class FromAirport : ContentPage
{
public FromAirport()
{
InitializeComponent();
}

    private void DatePicker_DateSelected(object sender, DateChangedEventArgs e)
    {

    }

    private void Button_Clicked(object sender, EventArgs e)
    {
        var emailMessenger = CrossMessaging.Current.EmailMessenger;
        if (emailMessenger.CanSendEmail)
        {
            var emailWithHtmlBody = new EmailMessageBuilder()
            .To("")
            .Subject("From Airport Reservation")
            .BodyAsHtml(htmlBody: "<b>Name: </b>" + Name.Text + "<br/><b>Address: </b>" + Address.Text + "<br/><b>Email: </b>" + emailAddress.Text + "<br/><b>Pickup Date: </b>" + PickupDate.Text + "<br/><b>Pickup Time: </b>" + PickupTime.Text + "<br/><b>Pickup Location: </b>" + PickupLocation.Text + "<br/><b>Phone: </b>" + PhoneNumber.Text + "<br/><b>Drop Off Location: </b>" + DropOff.Text + "<br/><b>Passengers: </b>" + Passengers.Text + "<br/><b>Bags: </b>" + Bags.Text + "<br/><b>Airline: </b>" + Airline.Text + "<br/><b>Flight Number: </b>" + FlightNumber.Text + "<br/><b>Comments: </b>" + Comments.Text)
            .Build();
            emailMessenger.SendEmail(emailWithHtmlBody);
        }
    }
}

}

Any help would be appreciated.... like i said i can view the picker and it will operate but no data moving to email..

thank you.
