Get an Attachment's Bytes into a BinData
See more Email Object Examples
Demonstrates the Chilkat Email.GetAttachmentBd method, which copies an attachment's binary data into a BinData object. The first attachment is at index 0. This example adds an attachment and copies its bytes into a BinData, printing the byte count.
Background: This is the safe, binary way to extract an attachment — the counterpart to the text-oriented
GetAttachmentString. Because attachments are often binary (PDFs, images, archives), copying the raw bytes into a BinData preserves them exactly, ready to write to a file, hash, or pass to another API without any charset conversion that could corrupt the data.Chilkat VB.NET Downloads
