title: Sending an email with attachment using SendGrid
body: <pre><code> var myMessage = new SendGridMessage();
              myMessage.From = new MailAddress("info@email.com");
              myMessage.AddTo("Cristian &lt;myemail@email.com&gt;");
              myMessage.Subject = user.CompanyName + "has selected you!";
              myMessage.Html = "&lt;p&gt;Hello World!&lt;/p&gt;";
              myMessage.Text = "Hello World plain text!";
  
             // myMessage.AddAttachment("C:\test\test.txt");
  
  
  
              var apiKey = "";
              var transportWeb = new Web(apiKey);
              transportWeb.DeliverAsync(myMessage);
  </code></pre>
  
  <p>Basically I can make the email work, and the moment I attempt to add an attachment it doesn't send it. I tried different paths and different ways of writing the path, I am not sure what is going wrong, every single tutorial I have found shows it should work like this.</p>
