Preface

This application is something I am doing as a personal practice project that relates to theme parks and rides.

Basically, we first have one of the objects that represents something I would take out of the database. This class is as follows:

public class Parks

{

    public int Id { get; }

    public string ParkValue{ get; set; }

    public string ParkName { get; set; }



}

Simple class, with 3 properties. Now, here is the data access that builds this based on an Id which comes from a different portion of the application.

public class ParkDataRetriever

{

    public Parks GetSelectedPark(Parks Park, int Id)

    {

        using (var Db = new MyContext())

        {

            List<ParkList> ListOfParks = Db.ParkLists.Where(x => x.ParkId == Id).ToList();



              var Parks = ListOfParks.Single();



                    Parks.ParkId = Park.Id;

                    Parks.ParkName = Park.ParkName;

                    Parks.DomValue = Park.DomValue;



                return Park;

        }

    }

}

So then in the application, we now have a type of class Parks that we can now use in the application.

Questions

Is this testable or is it too tightly coupled because of the using (var Db = new MyContext()) ?

For the sake of practice, I would want to pretend as if this was an application that would one day scale in size. So I imagine the more decoupled, the better off I am.

  If we should look past the loop then there is virtually nothing left to review. You need to post some real code that makes sense.

  @t3chb0t I guess I could just return single instead of doing the .toList(). I’m not really sure what difference it would make to remove the loop and just assign each property from a single result. I think the question still remains the same, cause are the property assignments really where tight coupling would take place, if it existed?
