Question

I am new to programming so I don’t know what the terminology is and I apologize. I want to be able to write something that looks like this:

Label Label1 = new Label();
Label1.Text = DateTime.Now.ToString("MM.dd.yyyy");

But with my own objects:

Reciept ReciptForAirPlaneTicket = new Reciept();
ReciptForAirPlaneTicket.MOP = MOP.CreditCard.Visa("4111111111111111|0815");

Reciept ReciptForFood = new Reciept();
ReciptForFood.MOP = MOP.CreditCard.MasterCard("4222222222222222|0917");

Reciept ReciptForClothes = new Reciept();
ReciptForClothes.MOP = MOP.Cash;

Reciept ReciptForTools = new Reciept();
ReciptForTools.MOP = MOP.Check("12345");

I really am not trying to be lazy, but I have been looking for almost a day now and I don’t even know what to look for. I think I need to make at least a class but also a struct or something called enum but I really don’t know.

I am using C#.

It seems like an unusual approach to me, but to get the exact syntax, you could create a kind of factory pattern using a static class MOP.

public class MethodOfPayment
{
    public enum enumCardType { Visa, Mastercard };
    public enum enumPaymentType { CreditCard, Cash };

    public string Number { get; set; }
    public enumPaymentType PaymentType { get; set; }
    public enumCardType CardType { get; set; }
}

public static class MOP
{
    public static class CreditCard
    {
        public static MethodOfPayment Visa(string number)
        {
            return new MethodOfPayment() { 
                Number = number,
                PaymentType = MethodOfPayment.enumPaymentType.CreditCard,
                CardType = MethodOfPayment.enumCardType.Visa
            };
        }
    }
}

Repeat for the other types, and then instantiate as required.

ReciptForAirPlaneTicket.MOP = MOP.CreditCard.Visa("4111111111111111|0517");
