示例

下面的代码示例显示了使用ChangePassword控件的 ASP.NET 页的代码隐藏示例，并包括名为SendingMail该SendingMail事件的事件处理程序。 此代码示例假定 ASP.NET 网站已配置为使用 ASP.NET 成员身份和表单身份验证，并且已创建一个用户，其名称和密码已知。 有关详细信息，请参阅 “如何：实现简单表单身份验证”。

如果密码更改成功，事件处理程序中的 SendingMail 代码将尝试向用户发送电子邮件以确认更改。 必须已在服务器上配置 SMTP 才能运行此代码示例。 有关如何配置 SMTP 服务器的信息，请参阅 如何：在 IIS 6.0 中安装和配置 SMTP 虚拟服务器。 出于此示例的目的，不需要配置 SMTP 服务器;该示例构造为测试未能发送电子邮件。

如果未正确配置邮件服务器或发生其他错误，并且无法发送电子邮件，则会调用该 SendMailError 函数。 向用户显示一条消息。 此外，事件将记录到 Windows 应用程序事件日志中，假设名为 MySamplesSite 的事件源已存在。 有关创建事件源的详细信息，请参阅 ASP.NET Web 窗体页中的服务器事件处理。 对象的 Handled 属性 SendMailErrorEventArgs 设置为 true 指示错误已处理。

下面的代码示例演示如何使用代码隐藏文件。
