MVC 3 中的自定义错误不起作用

Question

我正在尝试通过在我的 web.config 中指定自定义错误来使用 MVC 3 中的自定义错误页面。

我定义了一个 ErrorController，其中包含一个 Action 方法 Index()，用于处理应用程序中的所有错误

我的 web.config 如下所示：

<configuration>
<configSections>
 <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

</sectionGroup>
<sectionGroup name="elmah">
  <section name="errorMail" requirePermission="false"  type="Elmah.ErrorMailSectionHandler, Elmah"/>
  <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/>

  <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah"/>
</sectionGroup>
</configSections>

</customErrors>
<!--
    Enabling request validation in view pages would cause validation to occur
    after the input has already been processed by the controller. By default
    MVC performs request validation before a controller processes the input.
    To change this behavior apply the ValidateInputAttribute to a
    controller or action.

由于某种原因，当我的应用程序发生错误时，它没有触发我的 /Error/Index 操作。

这有什么明显的错误吗？有没有办法在 global.asax Application_Error() 中定义一个通用的错误消息操作方法？

您可以使用完全不同的机制，通过扩展 Elmah 将其绑定到标准 MVC 错误处理属性。这将允许您显示所有应用程序错误的 Error.cshtml 视图。
