Load collections with existing ChildIds using explicit loading

Question

Is it possible to explicit reload using existing Child Ids something like functionality of Reload() in DbEntityEntry ? See also comments in code.

using (var context = new MyContext())
{
    var parent = new Parent()
    {
        ParentId = 1,
        Childs = new List<Child>()
        {
            new Child()
            {
                ChildId = 2,
                ParentId = 1
            }
        }
    };

    context.Parents.Attach(parent);
    context.Entry(parent)
        .Collection(b => b.Childs) // Load only Employee with employee id of 2
        .Query()
        .Load(); //Is it possible to Reload only ChildId = 2?
}

Answer 1

Yes, it's possible, after Query method you can apply filters to the related entities you want to load:

 context.Entry(parent)
        .Collection(b => b.Childs) // Load only Employee with employee id of 2
        .Query()
        .Where(e=>e.ChildId==2)
        .Load();
