我正在尝试让 ASP.NET MVC 应用程序正常工作...我应该知道这并不容易。前几页有效，但它们都是静态的。第一次执行 Controller 时，出现以下异常。
这是 Controller 操作方法:
[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(Section? section, int? parent)
{
if (section == null)
{
return RedirectToAction("Index", "Questions", new {section = Section.Section0});
}
IPagedList<Question> questions = _surveyService.FetchQuestions(User.Identity.Name, section.Value, parent);
// ...
ViewResult result = View("Index", questions);
result.ViewData.Add("CurrentSection", section.Value);
result.ViewData.Add("Parent", parent);
result.ViewData.Add("IsLastPage", questions.IsLastPage);
return result;
}
在 RedirectToAction() 方法的第二行抛出异常。
背景:
- 我已按照 this answer 中的说明进行操作.
- 我没有在我的代码中明确使用反射或要求安全性。
- 我正在使用 MVC、LINQ to SQL，Elmah , 和 PagedList .
- 我正在使用 IIS 7 集成模式。
- 我添加了 [程序集: AllowPartiallyTrustedCallers] 到我的 AssemblyInfo.cs。我这样做是因为我发现另一个 Stack Overflow 问题有一个推荐它的答案(我现在找不到它，否则我会提供一个链接)。我还按照 Rex M 在下面的回答中建议的方式为我的程序集命名。
我缺少什么来完成这项工作？
