thank you

you need have property on view model hold selected answer when form posted:

public partial class question {     public int questionid { get; set; }     public string questionbody { get; set; }     public string correctanswer { get; set; }     public string alternativeanswer { get; set; }                 public string selectedanswer { get; set; } } 

and loop through elements of model , generated desired markup:

@model ilist<quiz.models.question>                                  <h2>welcome quiz</h2> @html.beginform( method:formmethod.post, controllername:"home", actionname:"index") {     @for (var = 0; < model.count; i++)     {         @html.hiddenfor(x => x[i].questionid)         <fieldset>             <legend>                 @html.displayfor(x => x[i].questionbody)             </legend>             <ul>                 <li>                     @html.hiddenfor(x => x[i].correctanswer)                     @html.radiobuttonfor(x => x[i].selectedanswer, model[i].correctanswer)                     @html.displayfor(x => x[i].correctanswer)                 </li>                 <li>                     @html.hiddenfor(x => x[i].alternativeanswer)                     @html.radiobuttonfor(x => x[i].selectedanswer, model[i].alternativeanswer)                     @html.displayfor(x => x[i].alternativeanswer)                 </li>             </ul>         </fieldset>     }      <button type="submit">ok</button> } 

note: when form submitted post action take ilist<question> model have answers each question (in selectedanswer property).
