System.Collections.Generic.List`1[test.Node]

Question

I have the following class named Node

 class Node
    {
        public int Id { get; set; }
        public int? ParentId { get; set; }
        public string         


        

Answer 1

Replace Children.ToString(); with:

string.Join(",", Children.Select(x => x.Id));

You are calling ToString on a IList<Node> so it's giving you the type name.If you want to see Ids of the child nodes you can use string.Join as shown above.
