IIS自定义错误未显示自定义错误页面

I have custom error pages setup on an ASP.NET website.

我在ASP.NET网站上设置了自定义错误页面。

There is one error that is not showing a custom error page, and just showing the usual yellow ASP.NET error page. If custom errors are turned on it shows "Server error in / application" / "Runtime error", but if custom errors are off it shows "validation of viewstate mac failed" error.

有一个错误没有显示自定义错误页面，只显示通常的黄色ASP.NET错误页面。如果启用了自定义错误，则会显示“服务器错误/应用程序”/“运行时错误”，但如果自定义错误已关闭，则会显示“viewstate mac failed验证失败”错误。

The relevant parts of my web.config are:

我的web.config的相关部分是：

<system.web>
  <compilation debug="false" targetFramework="4.0" />
    <customErrors mode="On" redirectMode="ResponseRewrite">
      <error statusCode="404" redirect="/404.aspx" />
      <error statusCode="500" redirect="/500.aspx" />
    </customErrors>

<system.webServer>
  <httpErrors errorMode="DetailedLocalOnly" />

To trap for this error do I have to use a different status code or substatuscode or is there something else?

要捕获此错误，我是否必须使用不同的状态代码或子代码或者还有其他什么？

After further research I see that this means that IIS is displaying the error rather than ASP.NET.

经过进一步研究后，我发现这意味着IIS正在显示错误而不是ASP.NET。

I changed the system.webServer part of my web.config so IIS can also use the custom error page and that has solved the problem.

我更改了web.config的system.webServer部分，因此IIS也可以使用自定义错误页面并解决了问题。

<system.webServer>
  <httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="500" subStatusCode="-1" />
    <error statusCode="500" subStatusCode="-1" responseMode="ExecuteURL" path="/500.aspx" />
  </httpErrors>
