{
    public int Id;
    public EntityContainer ParentContainer;
}


class EntityContainer
{
    public int Id;

        Entities.Add(entity);
    }
}


class Main
{
    public Main()
    {
        Entity entity1 = new Entity();
        Entity entity2 = new Entity();
        EntityContainer entityContainer = new EntityContainer();
        entityContainer.AddEntity(entity1);
        entityContainer.AddEntity(entity2);

        // Can now traverse graph easily, e.g.
        Console.WriteLine("entity1's parent container ID = " + entity1.ParentContainer.Id);
        Console.WriteLine("Container contains at least this entity ID: " …
