c# - Html.Action not work -

i want bring partial view of question link list edit view. however, when select groupby value, shows error below. please guide me.

the model item passed dictionary of type 'system.collections.generic.list1[<>f__anonymoustype42[surveytool.models.surv_question_ext_model,surveytool.models.surv_question_model]]', dictionary requires model item of type 'system.collections.generic.ienumerable`1[surveytool.models.surv_question_ext_model]'.

edit view:

@model ifxsurveytool.models.surv_main_model      <div class="question">              <h2>link</h2>              @html.action("questionlink", "surv_main", new { survey_id = model.survey_id })          </div> 

controller:

 public actionresult questionlink(int survey_id)         {             var query = r in db.surv_question_ext_model                         join s in db.surv_question_model on r.qext_question_id equals s.question_id                         s.question_survey_id == survey_id                         group new { r, s } r.qext_language grp                         select grp.firstordefault();              return partialview(query.tolist());         } 

questionlink view:

@model ienumerable<surveytool.models.surv_question_ext_model>  <br /> <table class="strip">      @foreach (var item in model)     {         <tr>             <td width="5%"></td>             <td>                 @html.actionlink("questionlink", "edit", "surv_answer", new { language = item.qext_language }, null)             </td>           </tr>     }  </table> 

please change following line in partialview code:

@model ienumerable<surveytool.models.surv_question_ext_model> 

to:

@model list<surveytool.models.surv_question_ext_model> 

or returning type in controller. types needs match.

from comments: there returned group of linq query, it's anoumous type, not 1 expecting.
