Get Extended Property from Google Contact using .Net Library

Hi Experts,

I am using this code to retrieve a list of contacts from Google Contacts

 public Feed<Contact> GetContacts()
        {
            //Provide Login Information
            RequestSettings rsLoginInfo = new RequestSettings("", Constants.GoogleAc.Username, Constants.GoogleAc.Password);
            rsLoginInfo.AutoPaging = true;

            // Fetch contacts and dislay them in ListBox
            cr = new ContactsRequest(rsLoginInfo);
            Feed<Contact> feedContacts = cr.GetContacts();

            return feedContacts;

        } //GetContacts

And I can successfully look up a lot of info, but I have created a custom field in my address book, and want to retrieve it. I can't work out how to access the Extended Properties?
Any ideas?

foreach (Contact ct in cts.Entries)
            {
                ContactDetails Ctct = new ContactDetails();
                Ctct.FirstName = ct.Name.GivenName;
                Ctct.LastName = ct.Name.FamilyName;
                Ctct.Email = ct.PrimaryEmail.Value;
                Ctct.Mobile = ct.PrimaryPhonenumber.Value;
                Ctct.TwitterName = ct.ExtendedProperties ***????
}

I am not sure about .Net but in general it should look like this:

Now I would think the Google address book API is similar to the Google calendar API

EventEntry myEntry = new EventEntry();

ExtendedProperty property = new ExtendedProperty();
property.Name = "http://www.example.com/schemas/2005#mycal.id";
property.Value = "1234";

entry.ExtensionElements.Add(property);

Therefore it would be

ct.ExtendedProperty.name.value
