Question

我在我的asp.net mvc 5应用程序中使用PagedList Nuget包。以下是我想要的来源：

@Html.PagedListPager(Model, page => Url.Action("StudentList",
new { page, sortOrder = ViewBag.CurrentSort, currentFilter = ViewBag.CurrentFilter }))

当我在我的观点中使用它时，它会抛出异常：

System.TypeAccessException was unhandled by user code
  HResult=-2146233021
  Message=Attempt by security transparent method 'PagedList.Mvc.HtmlHelper.PagedListPager(System.Web.Mvc.HtmlHelper, PagedList.IPagedList, System.Func`2<Int32,System.String>)' to access security critical type 'System.Web.Mvc.MvcHtmlString' failed.

Assembly 'PagedList.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=abbb863e9397c5e1' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model.  Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception.

  InnerException:

我试图在assemblyinfo.cs中使用这些属性

[assembly: SecurityRules(SecurityRuleSet.Level2)]

和

[assembly: AllowPartiallyTrustedCallersAttribute]但它没有用。请指导我。感谢

Answer 1

Nuget Package Manager， Update-Package PagedList.Mvc

我的问题已修复。

2级透明度导致AllowPartiallyTrustedCallers中的所有方法
