c# - POSTing self referencing model back to controller results in null object? -

is possible pass never ending self referencing model view controller? when submit form fiddler captures posting method settings[index].settings[index].value. actionresult save(settingsection settings) doesn't capture values being posted form. details below of code.

here self referencing model

public class settingsection : setting {     public list<settingsection> children { get; set; }     public list<settingsection> settings { get; set; }      #region public methods      public string getvalue(string path)     {         // find value json structure based on path         return "";     } 

here base class

public class setting {     #region fields      private string _name;     private string _text = "";     private string _description = "";     private string _enumerationname = "";     private string _overridevalue = null;     private datatype _settingtype;     private string _value;     private propertyinfo _propertyinfo;     private type _enumtype;      #endregion fields      #region constructors      public setting()     {     }      public setting(string name, datatype settingtype, string svalue)     {         _name = name;         _settingtype = settingtype;         _value = svalue;     }      #endregion constructors      #region public properties      public string description     {         { return _description; }         set { _description = value; }     }      public string enumerationname     {         { return _enumerationname; }         set { _enumerationname = value; }     }      public string name     {         { return _name; }         set { _name = value; }     }      public string text     {         { return _text; }         set { _text = value; }     }      public string caption     {         { return string.isnullorwhitespace(_text) ? _name : _text; }     }      public string overridevalue     {         { if (_overridevalue == null) return _value; return _overridevalue; }         set { _overridevalue = value; }     }      public datatype settingtype     {         { return _settingtype; }         set { _settingtype = value; }     }      public string value     {         { return _value; }         set { _value = value; }     }      #endregion public properties      #region public methods      #endregion public methods }
