注解

LoginError用户输入的凭据无效时引发事件。The LoginError event is raised when the credentials entered by the user are invalid. 可以使用LoginError事件以将用户重定向到自定义错误页,以提供更多帮助,或记录失败的登录尝试。You can use the LoginError event to redirect the user to a custom error page, to offer additional help, or to log failed login attempts.

有关如何处理事件的详细信息,请参阅处理和引发事件For more information about how to handle events, see Handling and Raising Events.
