C# 异步电子邮件发送isn'；不要返回视图

我的Asp.net网站上的忘记密码电子邮件链接有问题

基本上，一切正常，它发送一封电子邮件到帐户，密码可以重置，但我得到一个404错误，而不是返回正确的页面

public async Task<ActionResult> ForgotPassword(ForgotPasswordViewModel model)
{
    if (ModelState.IsValid)
    {
        var user = await UserManager.FindByEmailAsync(model.Email);

        if (user == null) // || !(await UserManager.IsEmailConfirmedAsync(user.Id)))
        {
            // Don't reveal that the user does not exist or is not confirmed
            return View("ForgotPasswordConfirmation");
        }

        // For more information on how to enable account confirmation and password reset please visit http://go.microsoft.com/fwlink/?LinkID=320771
        // Send an email with this link
        string code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
        var callbackUrl = Url.Action("ResetPassword", "Account", new { userId = user.Id, code = code }, protocol: Request.Url.Scheme);
        await UserManager.SendEmailAsync(user.Id, "Reset Password", "Please reset your password by clicking <a href=\"" + callbackUrl + "\">here</a>");
        return RedirectToAction("ForgotPasswordConfirmation", "Account");
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

在“电子邮件”部分，您应该会看到以下错误：“异步操作仍挂起时，异步模块或处理程序已完成”。我相信你得到404是因为可能没有找到错误页面

你可以试试下面的方法

public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        var mailMessage = new MailMessage("Email here",
            message.Destination,
            message.Subject,
            message.Body
            );

        var client = new SmtpClient();
        return client.SendMailAsync(mailMessage);
    }

或者使用等待/异步方式

public async Task SendAsync(IdentityMessage message)
        {

            // Plug in your email service here to send an email.
            var mailMessage = new MailMessage("Email here",
                message.Destination,
                message.Subject,
                message.Body
                );

            var client = new SmtpClient();
            await client.SendMailAsync(mailMessage);
        }

当您收到404时，我怀疑您发送电子邮件的呼叫失败，它试图显示错误消息，但未能找到错误视图。我会检查设置是否正确电子邮件每次都能完美发送？能否显示您的公共任务SendAsync（IdentityMessage message）实现？我已将其添加到原始代码中。谢谢你，先生，你是一个传奇：-）非常感谢

public Task SendAsync(IdentityMessage message)
    {
        // Plug in your email service here to send an email.
        var mailMessage = new MailMessage("Email here",
            message.Destination,
            message.Subject,
            message.Body
            );

        var client = new SmtpClient();
        return client.SendMailAsync(mailMessage);
    }

public async Task SendAsync(IdentityMessage message)
        {

            // Plug in your email service here to send an email.
            var mailMessage = new MailMessage("Email here",
                message.Destination,
                message.Subject,
                message.Body
                );

            var client = new SmtpClient();
            await client.SendMailAsync(mailMessage);
        }
