I have a class called Question that has a property called Type. Based on this type, I want to render the question to html in a specific way (multiple choice = radio buttons, multiple answer = checkboxes, etc...). I started out with a single RenderHtml method that called sub-methods depending on the question type, but I'm thinking separating out the rendering logic into individual classes that implement an interface might be better. However, as this class is persisted to the database using NHibernate and the interface implementation is dependent on a property, I'm not sure how best to layout the class.

The class in question:

public class Question
{
    public Guid ID { get; set; }
    public int Number { get; set; }
    public QuestionType Type { get; set; }
    public string Content { get; set; }
    public Section Section { get; set; }
    public IList<Answer> Answers { get; set; }
}

Based on the QuestionType enum property, I'd like to render the following (just an example):

<div>[Content]</div>
<div>
   <input type="[Depends on QuestionType property]" /> [Answer Value]
   <input type="[Depends on QuestionType property]" /> [Answer Value]
   <input type="[Depends on QuestionType property]" /> [Answer Value]
   ...
</div>

Currently, I have one big switch statement in a function called RenderHtml() that does the dirty work, but I'd like to move it to something cleaner. I'm just not sure how.

Any thoughts?
