电子邮件到文字不起作用

Question

我正在尝试将电子邮件作为文本发送给最终用户手机，代码运行正常，但我似乎无法收到短信。

这是我的代码

 public Task SendAsync()
    {
        var fromAddress = new MailAddress("test@gmail.com", "Authenticator");
        var toAddress = new MailAddress("mynumber@sms.sancharnet.in", "User");
        const string fromPassword = "mypassword";
        const string subject = "subject";
        string body = Session["PIN"].ToString();

        var smtp = new SmtpClient
        {
            Host = "smtp.gmail.com",
            Port = 587,
            EnableSsl = true,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = false,
            Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
        };

        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body,
            IsBodyHtml = false
        })
        {
            smtp.Send(message);
        }

        return Task.FromResult(0);
    }

我在这里缺少什么吗？或者这不是我们尝试通过电子邮件发送文本的方式吗？
