Mise à jour: Une signature de la méthode a changé .NET 4.5, qui rompt le ci-dessus:
L'Obtention De Système.Net.Mail.MailMessage comme un MemoryStream dans .NET 4.5 beta

C'est un très simple de mise en œuvre à l'aide de MimeKit

using Amazon;
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;
using MimeKit;
using System.IO;
namespace SendEmailWithAttachments
{
class Program
{
static void Main(string[] args)
{
//Remember to enter your (AWSAccessKeyID, AWSSecretAccessKey) if not using and IAM User with credentials assigned to your instance and your RegionEndpoint
using (var client = new AmazonSimpleEmailServiceClient("YourAWSAccessKeyID", "YourAWSSecretAccessKey", RegionEndpoint.USEast1))
using (var messageStream = new MemoryStream())
{
var message = new MimeMessage();
var builder = new BodyBuilder() { TextBody = "Hello World" };
message.From.Add(new MailboxAddress("[email protected]"));
message.To.Add(new MailboxAddress("[email protected]"));
message.Subject = "Hello World";
//I'm using the stream method, but you don't have to.
using (FileStream stream = File.Open(@"Attachment1.pdf", FileMode.Open)) builder.Attachments.Add("Attachment1.pdf", stream);
using (FileStream stream = File.Open(@"Attachment2.pdf", FileMode.Open)) builder.Attachments.Add("Attachment2.pdf", stream);
message.Body = builder.ToMessageBody();
message.WriteTo(messageStream);
var request = new SendRawEmailRequest()
{
RawMessage = new RawMessage() { Data = messageStream }
};
client.SendRawEmail(request);
}
}
}
}

J'ai le code dans mon référentiel https://github.com/gianluis90/amazon-send-email

J'ai aussi besoin d'aide, mais jusqu'à présent, j'ai trouvé, vous devez envoyer un message MIME multipart, avec la pièce jointe encodées en base64.
