Apex_mail.add_attachment

A Salesforce-specific question!

apex_mail.addAttachment is a method in Salesforce Apex that allows you to add an attachment to an email message. Here's a brief overview:

Syntax:

apex_mail.addAttachment(String attachmentBody, String attachmentName, String contentType)

Parameters:

1. attachmentBody: The binary data of the attachment.
2. attachmentName: The name of the attachment (e.g., "document.pdf").
3. contentType: The MIME type of the attachment (e.g., "application/pdf").

Example:

Here's an example of how you might use apex_mail.addAttachment to add an attachment to an email message:

// Create a new email message
Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

// Set the recipient and subject
mail.setToList(new String[] {'[email protected]'});
mail.setSubject('Test Email with Attachment');

// Create a binary attachment
Blob attachment = Blob.valueOf('Hello, World!');
String attachmentName = 'document.txt';
String contentType = 'text/plain';

// Add the attachment to the email message
apex_mail.addAttachment(attachment, attachmentName, contentType);

// Send the email message
Messaging.sendEmail(new Messaging.SingleEmailMessage[] {mail});

In this example, we create a new email message and set the recipient and subject. We then create a binary attachment using the Blob class and set its name and content type. Finally, we use apex_mail.addAttachment to add the attachment to the email message, and then send the email using Messaging.sendEmail.

Note that apex_mail.addAttachment can only be used in a Salesforce Apex class, and it's not available in Visualforce pages or Lightning components.
