Niedozwolone znaki na ścieżce. Błąd podczas korzystania z przejść i Take z IEnumerable

Question

Cześć Mam następujące działania w moim kontrolera

[AcceptVerbs(HttpVerbs.Post)] 
public ActionResult Index() 
{ 
    IEnumerable<SurveyResult> myresult = filterData(); 
    totalCount = myresult.Count<SurveyResult>(); 
    ViewBag.totalCount = totalCount; 
    //myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100); 
    return View(myresult); 
} 

Oto mój widok

@model IEnumerable<SurveyResult> 
@{ 
    ViewBag.Title = "Survey Results"; 
} 
@using (Html.BeginForm()) 
{ 

    <table class="std-tbl"> 
     <thead> 
      <tr> 
       <th> 
        DEL 
       </th> 
       ... 

       <th> 
       </th> 
      </tr> 
     </thead> 
     @Html.DisplayFor(x => x, new { pageIndex = ViewBag.index }) 
    </table> 
} 

Mam częściowy widok na SurveyResult ale nie jestem w tym ponieważ nie uważam, że jest to istotne. Oto moje pytanie. Powyższy kod działa poprawnie, ale jak tylko odkomentować następującą linię

myresult = myresult.Skip<SurveyResult>(100 * pageIndex).Take<SurveyResult>(100); 

otrzymuję „znaki nielegalne w ścieżce.” Myślę, że można go znaleźć PartialView dla SurveyResult. Nie rozumiem, dlaczego może go znaleźć, gdy powyższy wiersz zostanie skomentowany, ale nie może, kiedy zostanie odkomentowany? Dziękuję Ci.

jest mój stos ślad

Answer 1

DisplayFor szuka widoku nazwanego po imieniu EF-owych klas implementacji, które zawierają niedozwolone znaki.

Spróbuj zadzwonić pod numer .ToList() w kontrolerze.
