I'm searching for an working C# example to send attachments with Amazon-SES.
After reading that Amazon-SES now supports sending attachments I was searching for an C# example but was unable to find one.
I think that using AWS SDK for .NET and MimeKit is very easy and clean solution. You can send e-mails with attachments via SES API (instead of SMTP).
You can write MimeMessage directly to MemoryStream and then use it with SES SendRawEmail:
using Amazon.SimpleEmail;
using Amazon.SimpleEmail.Model;
using Amazon;
using Amazon.Runtime;
using MimeKit;
private static BodyBuilder GetMessageBody()
{
var body = new BodyBuilder()
{
HtmlBody = @"<p>Amazon SES Test body</p>",
TextBody = "Amazon SES Test body",
};
body.Attachments.Add(@"c:\attachment.txt");
return body;
}
private static MimeMessage GetMessage()
{
var message = new MimeMessage();
message.From.Add(new MailboxAddress("Foo Bar", "[email protected]"));
message.To.Add(new MailboxAddress(string.Empty, "[email protected]"));
message.Subject = "Amazon SES Test";
message.Body = GetMessageBody().ToMessageBody();
return message;
}
private static MemoryStream GetMessageStream()
{
var stream = new MemoryStream();
GetMessage().WriteTo(stream);
return stream;
}
private void SendEmails()
{
var credentals = new BasicAWSCredentials("<aws-access-key>", "<aws-secret-key>");
using (var client = new AmazonSimpleEmailServiceClient(credentals, RegionEndpoint.EUWest1))
{
var sendRequest = new SendRawEmailRequest { RawMessage = new RawMessage(GetMessageStream()) };
try
{
var response = client.SendRawEmail(sendRequest);
Console.WriteLine("The email was sent successfully.");
}
catch (Exception e)
{
Console.WriteLine("The email was not sent.");
Console.WriteLine("Error message: " + e.Message);
}
}
}
