Class that has a list of itself as a property

Question

I have the following class and wondered if it is allowed?

     public class Node
     {
        public string Type { get; set; }
        public string Id { get; set; }

        public string Text { get; set; }

        public string ParentNodeId { get; set; }

        public List<Node> TargetNodes { get; set; }
     }

The code compiles and even works but I am getting stack errors where I shouldn't be getting stack errors and wondered if it is because of my TargetNodes property? Should I create a new class for TargetNodes?

Answer 1

The problem was unrelated. I realised the function I was using to populate the nodes was calling itself and creating endless nodes in the list finding new targets and entering a loop.
