Demonstrates how to send an email with attachments.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The mailman object is used for sending (SMTP) and receiving (POP3) email.
Chilkat.MailMan mailman = new Chilkat.MailMan();

// Set the SMTP server.
mailman.SmtpHost = "smtp.my-tls-mail-server.com";

// Set the SMTP login/password (if required)
mailman.SmtpUsername = "MY_SMTP_USERNAME";
mailman.SmtpPassword = "MY_SMTP_PASSWORD";

// Connect to SMTP port 465 using TLS.
mailman.SmtpSsl = true;
mailman.SmtpPort = 465;

// Create a new email object
Chilkat.Email email = new Chilkat.Email();

email.Subject = "This is a test";
email.Body = "This is a test";
email.From = "Chilkat Support <support@chilkatsoft.com>";
bool success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com");
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

// Add some attachments.
// The AddFileAttachment method returns the value of the content-type it chose for the attachment.
string contentType = email.AddFileAttachment("qa_data/jpg/starfish.jpg");
if (email.LastMethodSuccess != true) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

contentType = email.AddFileAttachment("qa_data/pdf/fishing.pdf");
if (email.LastMethodSuccess != true) {
    Debug.WriteLine(email.LastErrorText);
    return;
}

// Call SendEmail to connect to the SMTP server and send.
// The connection (i.e. session) to the SMTP server remains
// open so that subsequent SendEmail calls may use the
// same connection.  
success = await mailman.SendEmailAsync(email);
if (success != true) {
    Debug.WriteLine(mailman.LastErrorText);
    return;
}

success = await mailman.CloseSmtpConnectionAsync();
if (success != true) {
    Debug.WriteLine("Connection to SMTP server not closed cleanly.");
}

Debug.WriteLine("Mail with attachments sent!");
