How to load inline image email attachments from byte array

Question

how to load inline images without storing in Disk.
We want to load the inline images in the byte array.

Answer 1

Both MailBuilder.AddAttachment and MailBuilder.AddVisual metods have overrides that take byte array as a parameter:

MimeData att = builder.AddAttachment(new byte[]{ (byte)'A'});
MimeData visual= builder.AddVisual(new byte[] {1,2,3});

Please note that as you don't pass file name anywhere, content-type is not recognized and file name is not set. You should do that manually:

att.FileName = "report.txt";
att.ContentType = ContentType.TextPlain;

visual.FileName = "image.jpg";
visual.ContentType = ContentType.ImageJpeg
