c# - 错误页面上的 ASP.net 捕获错误

Question

我已经设置了可以正常工作的自定义错误页面:

<customErrors mode="On"  redirectMode="ResponseRewrite">
  <error statusCode="500" redirect="~/Pages/ErrorPages/500.aspx" />
</customErrors>

在 500.aspx 上:

    Response.ClearContent();
    Response.StatusCode = 500;
    Exception = Server.GetLastError();
    Code.Errors.Error.RecordNewError(ErrorType.InternalException, Exception, Code.Common.GetUserIPAddress().ToString(), HttpContext.Current);
    Server.ClearError();

问题是，如果错误页面本身抛出错误，我们会得到一个难看的错误:

Runtime Error

Description: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.

如果错误页面本身抛出错误，我如何回退到更基本的自定义错误页面？

刚刚想通了!在错误页面本身上使用 Page_Error 方法:

    private void Page_Error(object sender, EventArgs e)
    {
        Response.ClearContent();
        Response.StatusCode = 500;
        Exception = Server.GetLastError();
        HttpContext.Current.Response.Write("Error");
        HttpContext.Current.Response.End();
    }
