Question

From a fresh MVC 3 Project, I ve modified an Index() action to throw an exception. I expect the stock Error.chhtml view to be rendered, because I ve set <customErrors mode="On" /> in the web.config. Instead, I still get the "yellow screen of death" while running from within VS.

<system.web>
  <customErrors mode="On" />
  ...

My HandleError attribute is set globally from the global.asax.cs.

    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
    }

...unmodified, per the default project setup. I ve run against both IIS express and VS Dev Server. Nothing causes the custom error page to surface. What am I missing?

Answer 1

我也看到了同样的问题,因为我增加了customErrors model=On” >至<root>ViewsWeb.config,而不是<root>Web.config。

Answer 2

你们使用什么网络服务器? IIS7在网上使用一个不同的部分,认为可能是你的问题。

See this: What is the difference between customErrors and httpErrors?

Answer 3

 <system.web>
    <customErrors mode="On" defaultRedirect="Error.html">
        <error statusCode="403" redirect="/Error403" />
        <error statusCode="404" redirect="/Error404" />
        <error statusCode="500" redirect="/Error500" />
    </customErrors>
</system.web>
<system.webServer>
  <httpErrors errorMode="Custom" existingResponse="Auto" defaultResponseMode="ExecuteURL" >
    <remove statusCode="403"/>
    <remove statusCode="404"/>
    <remove statusCode="500"/>
    <error statusCode="403" responseMode="ExecuteURL" path="/Error403" />
    <error statusCode="404" responseMode="ExecuteURL" path="/Error404" />
    <error statusCode="500" responseMode="ExecuteURL" path="/Error500" />
  </httpErrors>
</system.webServer>
