Elmah - 捕获错误,但仍然记录并发送电子邮件？

Question

首先,我发现你可以捕获它并将其记录在catch中,但这不会发送电子邮件.然后我发现了使用这门Error Signal课程.这有用,但是从阅读中看不出来的是,它将错误视为正常,因此当我发出错误信号时,它仍会转到自定义错误页面,我不希望这种情况发生.

我想要做的是捕获该错误,记录它,发送电子邮件,但保持在页面上发生错误,以便我可以提供特殊反馈.我不希望它转到自定义错误页面.

我怎么能做到这一点？

编辑:这是我拥有的,它将我重定向到自定义错误页面.

    Try
        smtpClient.Send(mailMessage)
    Catch smtpEx As SmtpException
        errorSignal.FromCurrentContext().Raise(smtpEx)
    Catch ex As Exception
        errorSignal.FromCurrentContext().Raise(ex)          
    End Try

编辑:发布涉及Elmah的web.config部分(除了连接字符串hah)并且我的Global.asax文件中没有涉及Elmah的内容.

以下应该工作(我做你正在谈论的完全相同的事情)

try {
  // do something
} catch (Exception ex) {
  Elmah.ErrorSignal.FromCurrentContext().Raise(ex); // logs and sends the error through elmah
  // write a message to the user
}

如果你想要一个很好的框架来显示消息,你可以查看smokesignals(免责声明:这是我的工作)
