Unzulässige Zeichen im Pfad. Fehler bei der Verwendung von Überspringen und Nehmen mit IEnumerable

Question

Hallo zusammen habe ich die folgende Aktion in meinem Controller

[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); 
} 

Hier ist meine Ansicht

@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> 
} 

Ich habe eine Teilansicht für SurveyResult aber ich bin nicht inklusive weil ich es nicht für relevant halte. Hier ist meine Frage. Der obige Code funktioniert gut, aber sobald ich die folgende Zeile Kommentar-

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

erhalte ich „Ungültige Zeichen in Pfad.“ Ich denke, es ist die PartialView für SurveyResult zu finden. Ich verstehe nicht, warum es es finden kann, wenn die obige Zeile kommentiert ist, aber es kann nicht, wenn es unkommentiert ist? Vielen Dank.

Hier ist mein Stack-Trace

Here is the source Error:

Answer 1

DisplayFor sucht nach einer Ansicht benannt nach dem Namen der EF-generierten Implementierungsklassen, die ungültige Zeichen enthalten.

Versuchen Sie, .ToList() in der Steuerung aufzurufen.
