Hi,

I have an simple MVC app that is currently sending email using SMTP.

I have now migrated the app to Azure and the SMTP no longer works.  

I have to use SendGrid now but I am not sure how I need to change the code in order to use the new SendGrid method.  I don't want to have to re-write my entire current email page if its unessarsary.

Here is the guide I'm using:

https://azure.microsoft.com/en-gb/documentation/articles/sendgrid-dotnet-how-to-send-email/

I completed up until the code part.

Here's my current email.cs page in its entirety..


using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Mail;
using System.Web;
using System.Web.Configuration;
using SendGrid;



namespace smashandgrab
{
    public class EmailSender
    {
        string EmailSenderId = WebConfigurationManager.AppSettings["EmailSenderId"];
        string EmailSenderPassword = WebConfigurationManager.AppSettings["EmailSenderPassword"];
        string EmailSenderEnableSsl = WebConfigurationManager.AppSettings["EmailSenderEnableSsl"];
        string EmailSenderHost = WebConfigurationManager.AppSettings["EmailSenderHost"];
        string EmailSenderPort = WebConfigurationManager.AppSettings["EmailSenderPort"];
        string SenderTitle = WebConfigurationManager.AppSettings["SenderTitle"];
        string emailBody = "";






        public void SendEmail(DataResult obj)
        {
            string path = HttpContext.Current.Server.MapPath("/EmailFormat/EstimationEmail.html");

            if (File.Exists(path))
            {
                emailBody = File.ReadAllText(path);
                emailBody = emailBody.Replace("#FloorDepth#", obj.FloorDepth);
                emailBody = emailBody.Replace("#val220#", obj.val220);
                emailBody = emailBody.Replace("#val240#", obj.val240);
                emailBody = emailBody.Replace("#val300#", obj.val300);
                emailBody = emailBody.Replace("#Include1#", obj.Include1);
                emailBody = emailBody.Replace("#Include2#", obj.Include2);
                emailBody = emailBody.Replace("#Include3#", obj.Include3);
                emailBody = emailBody.Replace("#Include4#", obj.Include4);
                emailBody = emailBody.Replace("#Include5#", obj.Include5);
                emailBody = emailBody.Replace("#Include6#", obj.Include6);
                emailBody = emailBody.Replace("#Include7#", obj.Include7);
                emailBody = emailBody.Replace("#Include8#", obj.Include8);
                emailBody = emailBody.Replace("#Include9#", obj.Include9);
                emailBody = emailBody.Replace("#Include10#", obj.Include10);

            }

            using (MailMessage mail = new MailMessage())
            {
                mail.DeliveryNotificationOptions = System.Net.Mail.DeliveryNotificationOptions.OnSuccess;
                mail.From = new MailAddress(EmailSenderId);
                mail.To.Add(obj.Email);
                mail.Subject = "Quote";
                mail.Body = emailBody;
                mail.IsBodyHtml = true;  
                MailAddress mailaddress = new MailAddress(EmailSenderId, SenderTitle);
                mail.From = mailaddress;
                using (SmtpClient smtp = new SmtpClient(EmailSenderHost, Convert.ToInt32(EmailSenderPort)))
                {
                    smtp.Credentials = new NetworkCredential(EmailSenderId, EmailSenderPassword);
                    smtp.EnableSsl = Convert.ToBoolean(EmailSenderEnableSsl);
                    smtp.Send(mail);
                }
            }
        }
    }
}

code looks ok.. Are you getting any error?

do u have the correct smptp address/port


This is wht send grid uses:

host:smtp.sendgrid.net
port:587

it would be better if you use their api's for sending emails, then you can track the emails as well whether it was delivered correctly and so on

Hi Gautham,

Thank for the advice :)

I am trying to use the sendgrid API but am having some problems.

I am using this guide:

https://azure.microsoft.com/en-gb/documentation/articles/sendgrid-dotnet-how-to-send-email/


I've followed the guide perfectly but I get the errors:

Error

I think I've just got myself in a muddle with my old smtp code and the new sendgrid code :(

here is the code in my email.cs file:

The old SMTP method is commented at the bottom.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Mail;
using System.Web;
using System.Web.Configuration;
using SendGrid;



namespace smashandgrab
{
    public class EmailSender
    {
        string EmailSenderId = WebConfigurationManager.AppSettings["EmailSenderId"];
        string EmailSenderPassword = WebConfigurationManager.AppSettings["EmailSenderPassword"];
        string EmailSenderEnableSsl = WebConfigurationManager.AppSettings["EmailSenderEnableSsl"];
        string EmailSenderHost = WebConfigurationManager.AppSettings["EmailSenderHost"];
        string EmailSenderPort = WebConfigurationManager.AppSettings["EmailSenderPort"];
        string SenderTitle = WebConfigurationManager.AppSettings["SenderTitle"];
        string emailBody = "";






        public void SendEmail(DataResult obj)
        {
            string path = HttpContext.Current.Server.MapPath("/EmailFormat/EstimationEmail.html");





            if (File.Exists(path))
            {
                emailBody = File.ReadAllText(path);
                emailBody = emailBody.Replace("#FloorDepth#", obj.FloorDepth);

            // Send the email, which returns an awaitable task.

            //        smtp.Send(mail);
            //    }
            //}
        }
    }

this is how i did in one of my apps

public static bool SendEmail(string toList, string subject, string body, string fromAddress, string fromName, string apiKey)
        {
            try
            {
                SendGridMessage myMessage = new SendGridMessage();
                myMessage.AddTo(toList);
                myMessage.From = new MailAddress(fromAddress, fromName);
                myMessage.Subject = subject;

                myMessage.Html = body;
                var transportWeb = new Web(apiKey);
                var task = transportWeb.DeliverAsync(myMessage);
                task.Wait();
                return task.IsCompleted;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

Yes.

"the type or namespace 'SendGridMessage' ....


What is annoying is that its my only option for sending emails using Azure!  Even MS support can't help me!

Frustrating !

can you try exploring this dll "SendGridMail.dll" and see if you can find this class?

Only thing different is that you are on a higher version than mine (urs is 8 and mine is 6)

I found it thanks to you!  

I was using the wrong version of sendgrid.   I downgraded my version to 6.2.4 and now the SendGridMail is available.

Thank you for all your help.
