asp.net mvc - [HttpPost]public ActionResult Create(FormCollection collection) VERSUS [HttpPost]public ActionResult Create(Dinner dinner) -

in scott hanselman's book (chapter 1), provides 2 options implement [httppost] create action method.

the first 1 relies on tryupdatemodel update model object based on incoming form fields. when incoming form fields contains invalid input, modelstate.isvalid set false.

        [httppost]         public actionresult create(formcollection collection)         {             dinner dinner = new dinner();              if (tryupdatemodel(dinner))             {                 dinnerrepository.add(dinner);                  dinnerrepository.save();                  return redirecttoaction("details", new { id = dinner.dinnerid });             }             else                 return view(dinner);          } 

---

the second method utilize model passed create action method arg follows:

        [httppost]         public actionresult create(dinner dinner)         {             if (modelstate.isvalid)             {                 dinnerrepository.add(dinner);                  dinnerrepository.save();                  return redirecttoaction("details", new { id = dinner.dinnerid });             }             else                 return view(dinner);         } 

which 1 more recommended use in production ?

if required data either in request.form, route data, or url query string, can use model binding in second example.

the model binder creates dinner object , populates data request matching property names.

you can customize binding process “white lists”, “black lists”, prefixes, , marker interfaces. make sure don't unintentionally bind values – see link.
