Mapping readonly child collection with AutoMapper

Question

It\'s not so much a question, as I have found a way to do what I want, but it seems like there should be a better way to do it. I\'ve searched everywhere and not found anything.

Answer 1

I don't like to have logic inside property getter or setter, but what about adding setter to Children property of Parent class

public class Parent
{
    private readonly IList _children = new List();

    public IEnumerable Children
    {
        get => _children;
        set => AddChildren(value);
    }

    public void AddChild(Child child)
    {
        child.Parent = this;
        _children.Add(child);
    }

    private void AddChildren(IEnumerable children)
    {
        _children.Clear();

        foreach (var child in children)
        {
            AddChild(child);
        }
    }
}

And AfterMap logic is not more necessary. Mapping configuration will be simple

Mapper.CreateMap();
