Question

我正在尝试使用C＃Windows应用程序从Gmail帐户向airtel mobile（在卡纳塔克邦）发送免费短信。邮件已发送，我可以看到已发送的邮件，但手机未收到该邮件。

这是我的代码，

SmtpClient smtp = new SmtpClient();
smtp.Credentials = new NetworkCredential("youraccount@gmail.com", "activedust");          
smtp.Port = 587;
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network; 
MailMessage message = new MailMessage();

message.To.Add("919845no@airtelkk.com");//replace  no with airtel mobile number in Karnataka

message.From = new MailAddress("youraccount@gmail.com", "App",System.Text.Encoding.UTF8);
message.Body = "type your body";
message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
smtp.send(message);

我可以使用此代码成功发送电子邮件，但短信无效

Answer 1

您必须在上述手机号码上激活此服务。如果它没有被激活，那么你将不会在手机上接收短信需要49 / - 费用或类似的东西。

如果未激活，您可以激活并再次尝试

一种方法是使用您的Gmail帐户发送短信

using System.Net;
using System.Net.Mail;

public void SendTextMessage(string subject, string message, long telephoneNumer)
        {
            // login details for gmail acct.
            const string sender = "me@gmail.com";
            const string password = "mypassword4gmailacct";

            // find the carriers sms gateway for the recipent. txt.att.net is for AT&T customers.
            string carrierGateway = "txt.att.net";

            // this is the recipents number @ carrierGateway that gmail use to deliver message.
            string recipent = string.Concat(new object[]{
            telephoneNumer,
            '@',
            carrierGateway
            });

            // form the text message and send
            using (MailMessage textMessage = new MailMessage(sender, recipent, subject, message))
            {
                using (SmtpClient textMessageClient = new SmtpClient("smtp.gmail.com", 587))
                {
                    textMessageClient.UseDefaultCredentials = false;
                    textMessageClient.EnableSsl = true;
                    textMessageClient.Credentials = new NetworkCredential(sender, password);
                    textMessageClient.Send(textMessage);
                }
            }
        }
