Question

Well, I need to create two questionnaires that are almost equals. The difference are that one have a question more than the other. So I created a class with only the ID (to persistence) to be the base class for both:

public class BaseQuizzClass{
    public int ID {get;set;}
} 

And then I created the classes, with almost the same names for the variables ( I thought that it could help using razor):

public class Quizz1 : BaseQuizzClass{

   [Display(Name="QuestionHere")]
   public string q1 {get;set;}

   [Display(Name="QuestionHere")]
   public string q2 {get;set;}

   ...

   [Display(Name="QuestionHere")]
   public string q9 {get;set;}
}

public class Quizz2 : BaseQuizzClass{
   [Display(Name="QuestionHere")]
   public string q1 {get;set;}

   [Display(Name="QuestionHere")]
   public string q2 {get;set;}

   ...

   [Display(Name="QuestionHere")]
   public string q9 {get;set;}

   [Display(Name="QuestionHere")]
   public string q10 {get;set;}
}

Then I created a View using the BaseQuizzClass as model, so I could pass an child class as parameter toit. But I don’t know how to access the childs class attributes.

OBS.: Each question has your own text, defined in the Display annotation.

There’s any way to do what I want? (I’m not pretty sure if I was clear)

Answer 1

I would probably switch the model up a bit:

public class QuestionClass
{
  public String Question { get; set; }

  public String Answer { get; set; }
}

public class QuizzClass
{
  public Int32 ID { get; set; }

  [UIHint("Question")]
  public IList<QuestionClass> Questions { get; set; }
}

Then create a view for the question, and instead of using the [DisplayAttribute] using the “key/value” setup of the object.

// ~/Views/_controller_/_action_.cshtml
@model QuizzClass

@using (Html.BeginForm())
{
  for (var q = 0; q < Model.Questions.Length; q++)
  {
    // ~/Views/Shared/EditorTemplates/Question.cshtml
    @Html.EditorFor(x => Model.Questions[q]);
  }
}

It just appears over-kill to have that much similarity, yet explicitly calling out each question in your “different” objects.
