Question

我使用等待功能来发送电子邮件。有什么解决方案，如何在等待功能完成时显示页面或返回view（）。

这是我的代码：

 using (var smtp = new SmtpClient())
                {
                    var credential = new NetworkCredential
                    {
                        UserName = "email@gmail.com",
                        Password = "paswordEmail"
                    };
                    smtp.Credentials = credential;
                    smtp.Host = "smtp-mail.outlook.com";
                    smtp.Port = 587;
                    smtp.EnableSsl = true;
                    await smtp.SendMailAsync(message); //Here is my await function for sending an email
                    return RedirectToAction("ThankYou"); //This thank you page. I want to display this html page without waiting for await complete
                }

您可以将邮件代码包装在Task.Run中，而不必等待它。

Task.Run(async () => {
    using (var smtp = new SmtpClient()) {
        var credential = new NetworkCredential {
            UserName = "email@gmail.com",
            Password = "paswordEmail"
        };
        smtp.Credentials = credential;
        smtp.Host = "smtp-mail.outlook.com";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        await smtp.SendMailAsync(message); //Here is my await function for sending an email
    }
});
return RedirectToAction("ThankYou");

ASP.NET具有执行后台工作的专用工具：https://laravel.com/docs/5.7/queries#increment-and-decrement。

只需在此处发布您的作品即可

HostingEnvironment.QueueBackgroundWorkItem(
    async () =>
    {
        using (var smtp = new SmtpClient
            {
                Host = "smtp-mail.outlook.com",
                Port = 587,
                EnableSsl = true,
                Credentials = new NetworkCredential
                {
                    UserName = "email@gmail.com",
                    Password = "paswordEmail",
                },
            })
        {
            await smtp.SendMailAsync(message); //Here is my await function for sending an email
        }
    });
return RedirectToAction("ThankYou");
