c# - Automapper parent-child self referencing loop -

i'm trying map list model object kid has reference parent. json serialization throw "self referencing loop detected" error message. model classes:

public class event { public int id { get; set; } public string name { get; set; } public icollection<eventelement> eventelements { get; set; } ... } public class eventelement { public int id { get; set; } ... public int eventid { get; set; } public virtual event event { get; set; } }

i had tried tricks in automapper configuration. first, throw same error: mapper.createmap() .formember(vm => vm.eventelements, opt => opt.mapfrom(src => src.eventelements));

second, homecoming null each object in list: mapper.createmap().maxdepth(1);

how can event info childs without circular loop?

you need disable proxy creation in dbcontext below:

dbcontext.configuration.proxycreationenabled = false;

and utilize "include" lambda look in repository

public iqueryable<customer> getallcustomers() { homecoming dbset.asqueryable().include(s => s.statustype).include(s => s.customercategory); }
