通过sendgrid c发送短信时尚未发送完整短信息＃

Question

我希望使用发送网格通过短信网关发送短信。 我正在使用以下代码发送短信。

var sendgrid_message = new SendGridMessage();

sendgrid_message.AddTo(toNumber@domainname);

//set the sender
sendgrid_message.From = new MailAddress(from_address);

//set the message body
// sendgrid_message.Html = message;
sendgrid_message.Html = string.Format(" ");

//set the message subject
sendgrid_message.Subject ="The profile has been updated successfully. If you have not done this, please contact administrator.";

sendgrid_message.Text = "The profile has been updated successfully. If you have not done this, please contact administrator.";

//create an instance of the Web transport mechanism
var transportInstance = new Web(new NetworkCredential(username, password));

//send the mail
await transportInstance.DeliverAsync(sendgrid_message);

但我没有收到短信中的完整内容。 我按照以下方式收到了消息

'The profile has been updated successfully. If you
'

即使我也使用SMTP，我也没有获得完整的内容。

我哪里错了？

我是否需要按照其他方式发送短信？

请告诉我。
