How do i create nested json? - json

Question

Help please. I am trying to use Newtonsoft to serialize the following and can't get it to work. The resulting JSON should look like this Extract from Postman. I just cannot figure out how to structure the adding of the data before running the serialization
Anyone able to point me in the right direction?

You need the set properties of the objects:
ItemRef itemRef = new ItemRef();
itemRef.value = "1";
SalesItemLineDetail salesItemLineDetail = new SalesItemLineDetail();
salesItemLineDetail.ItemRef = itemRef;
Line line = new Line();
line.Id = "1";
line.LineNum = 1;
line.SalesItemLineDetail = salesItemLineDetail;
Root root = new Root();
root.Line = new List<Line>();
root.Line.Add(line);
string body = JsonConvert.SerializeObject(root);
