How to use System.Lazy with Setter to Lazy Initialization of List in POCO Entities?

Question

I want to use System.Lazy to Lazy Initialization of my List in my Entites:

public class Questionary
{
    private Lazy> _questions = n         


        

Answer 1

You could do something like this:

public class Questionary
{
    private Lazy> _questions = 
        new Lazy>(() => new List());

    public IList Questions
    {
        get { return _questions.Value; }
        set { _questions = new Lazy>(() => value); }
    }
}

However, I don't see why you need Lazy here at all. There is no benefit in using it, because the initialization of a new List should be the same as the initialization of a new Lazy...

I think it would be enough to keep it as simple as this:

public class Questionary
{
    private IList _questions = new List();

    public IList Questions
    {
        get { return _questions; }
        set { _questions = value; }
    }
}

or

public class Questionary
{
    public Questionary()
    {
        Questions = new List();
    }

    public IList Questions { get; set; }
}
