Question

I have a class that has 2 properties and a constructor:

public class Card
{
    public int CardName {get;set;}
    public bool IsActive {get;set;}

    public Card (int cardName, bool isActive)
    {
        CardName = cardName;
        IsActive = isActive;
    }
}

How do I force the developer to use the constructor instead of doing the following:

var card = new Card{ CardName = "blab", IsActive = true };

On a side note, what is the statement above called? Is that a lazy loading statement?

Answer 1

You already have.

By not having an empty constructor you’ve removed the ability to use the object initializer method of creating an object.

This:

var card = new Card{ CardName = "blab", IsActive = true };

is the same as this

var card = new Card() { CardName = "blab", IsActive = true };

And in this context new Card() is not valid.
