Add a String Attachment to an Email

See more Email Object Examples

Demonstrates the Chilkat Email object's AddStringAttachment method, which adds an attachment directly from an in-memory string — no file needs to exist on disk. The 1st argument is the filename that is written into the MIME (it is not a path to a file that is read), and the 2nd argument is the text that becomes the attachment's body. In this example we build a simple email, attach a small CSV file named people.csv straight from a string, and then print the resulting MIME so you can see the attachment embedded in the message.

// This example demonstrates the Email object's AddStringAttachment method.
// AddStringAttachment adds an attachment directly from an in-memory string.
// The 1st argument is the filename to be placed in the MIME (not a file to be read).
// The 2nd argument is the text content that becomes the attachment body.

let email = chilkat::Email::new();

email.set_subject("Email with a string attachment");
email.set_body("See the attached CSV file.");
email.set_from("mary@example.com");
let _ = email.add_to("Joe", "joe@example.com");

// The text content of the attachment.
let csv_data = "id,name\r\n1,Alice\r\n2,Bob\r\n".to_string();

// Add the string as an attachment named "people.csv".
let _ = email.add_string_attachment("people.csv", &csv_data);

// Show the full MIME of the email, which now includes the attachment.
println!("{}", email.get_mime().unwrap_or_default());
