Question

如果我将mail.Dispose()放在最后，SendMailAsync()完成其通话后，是否会始终调用mail.Dispose()？例如，如果我呼叫Post()一千次，则应在每封电子邮件发送后调用dispose。

这是我的代码：

public async Task Post(NotificationData notification)
{
    MailMessage mail = new MailMessage();
    mail.To.Add(new MailAddress(notification.Email));
    mail.Subject = notification.Subject;
    mail.Body = notification.Body;

    using (SmtpClient smtp = new SmtpClient())
    {
        smtp.SendCompleted += new SendCompletedEventHandler(SmtpClient_SendCompleted);
        await smtp.SendMailAsync(mail);
    }

    mail.Dispose();
}

public async Task Post(NotificationData notification)
{
    using (MailMessage mail = new MailMessage())
    {
        mail.To.Add(new MailAddress(notification.Email));
        mail.Subject = notification.Subject;
        mail.Body = notification.Body;

        using (SmtpClient smtp = new SmtpClient())
        {
            smtp.SendCompleted += new SendCompletedEventHandler(SmtpClient_SendCompleted);
            await smtp.SendMailAsync(mail);
        }
    }
}

异步发送电子邮件并进行处理
