   UpdatePanelCreateUser.Update();

【问题讨论】：

进入您的代码 - 特别是 CreateUserWizard1_SendingMail1 方法，因为这是您在面板上调用 Update() 方法的地方。有可能其中的某些内容引发了错误，从而导致您收到消息。

谢谢蒂姆，是的，我检查过，但每件事都很顺利，结束块断点被命中，没有任何问题。

什么触发更新面板更新？

谢谢@SollyM 这个问题已经解决了。实际上在发送邮件完成执行后出现异常。因此，除了 Application_Error 之外，没有办法捕获该异常。因此，我转到 CreatedUserWizard 并尝试从那里手动发送邮件并捕获异常（如果有）以手动取消 createduser 并删除任何创建的用户。谢谢你的提问:)

甜蜜。然后把这个作为你的答案，这样这篇文章就可以完成了。

问题已解决。实际上，sendingmail 执行完成后出现异常。所以除了Application_Error，没有办法捕捉到这个异常。所以我搬到CreatedUser 并尝试从那里手动发送邮件并捕获异常（如果有）手动取消createduser 并删除任何创建的用户。
