Remove a Single Attachment from an Email

Demonstrates the Chilkat Email.DropSingleAttachment method, which removes the attachment at the specified zero-based index. Valid indexes run from 0 through NumAttachments - 1. This example adds two attachments, removes the first, and prints the count before and after.

Background: Attachments are addressed by a zero-based index, so the first is 0, the second 1, and so on. DropSingleAttachment removes just one — use it to prune a specific file (say, an oversized or unwanted attachment) while keeping the rest. Note that after a removal the remaining attachments shift down, so if you are deleting several by index, iterate from the highest index downward to avoid skipping any.
