c# - Global_Asax Application_Error Fired 而不是默认的 IIS7 404 Page Not Found Page

Question

我有一个具有 Global_Asax 和自定义错误页面的 Web 应用程序。当用户尝试进入不存在的无效页面时，会在 Global_asax 中触发 Application_Error 并记录异常，这并不是真正的异常(您可以在下面查看异常详细信息)。我不想在 global_asax 中处理这种情况，而是在 IIS 中处理。我还尝试输入以 .asp 和 .html 结尾的无效路径，它们工作正常(它们不是以 global_asax 结尾，而是以默认 404 页面结尾)。

我需要知道我必须从 IIS7 管理器更改哪些设置。

如有任何帮助，我们将不胜感激。

Answer 1

您可以尝试其中之一:

1. 为自定义错误编辑 web.config 文件:

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

2. 添加一个 404.aspx 页面并将状态代码设置为 404:

   public partial class _04 : System.Web.UI.Page
   {
       protected void Page_Load(object sender, EventArgs e)
       {
           Response.StatusCode = 404;
       }
   }
   

如果它不能帮助你也试试这个(它可能会被你的主页重置):

protected override void Render(HtmlTextWriter writer)
{
    base.Render(writer);
    Response.StatusCode = 404;
}
