asp.net 不显示配置的自定义 404 页面

在我的网络配置中我有：

<customErrors mode="On">
  <error statusCode="404" redirect="~/error/404.aspx" />
</customErrors>

http://localhost/meh http://localhost/meh

http://localhost/meh.aspx http://localhost/meh.aspx

http://localhost/error/404.aspx http://localhost/error/404.aspxall404错误

我必须如何设置 web.config 才能将所有 404 发送到我的自定义错误？

Thanks

You have to configure this in IIS. By default, only specific files will get routed through the ASP.NET framework... otherwise IIS will handle it.
