first of all, have create these classes,

public class result {     public list<tablea> { get; set; } } public class tablea {     public tablea()     {           b = new list<tableb>();           c = new list<tablec>();     }     public string id { get; set; }     public string type { get; set; }     public string name { get; set; }     public float ppu { get; set; }     public virtual list<tableb> b { get; set; }     public virtual list<tablec> c { get; set; } }  public class tableb {     public string id { get; set; }     public string type { get; set; } } public class tablec {     public string id { get; set; }     public string type { get; set; } } 

after then, store values in result object of result class , serialize using newtonsoft serializer mentioned below:

result result; jsonconvert.serializeobject(result);
