How to serialize list of class type?

Question

C++ / C#

I need to serialize the list of the RootObject class, I tried a lot, I can’t serialize, I visited a simple record, the file doesn’t come out, can you tell me even?

public class Section
  {
    public string type { get; set; }
    public string group { get; set; }
    public int count { get; set; }
    public string name { get; set; }
    public string displaytype { get; set; }
    public List<object> data { get; set; }
    
  }

  public class RootObject
  {
    public string xmlns { get; set; }
    public string status { get; set; }
    public string version { get; set; }
    public int webplayer { get; set; }
    public string responsetype { get; set; }


    public List<Section> sections { get; set; }
  }
      var obj = JsonConvert.DeserializeObject<RootObject>(bn);

Answer 1

To serialize a list, you need to make sure that your Section class is also serializable. If it's serializable - at least you can serialize each element of the list in turn in a loop.

Answer 2

JsonConvert.SerializeObject(new RootObject().sections);

What is the problem?
