As title.
I'm developing a system that can send a QR Code image to a member via e-mail. I want to build it in a Web Service for usage of many clients. The current method I use is saving the QR Code to be a real image file, and attaching it when sending e-mail, but failed when I use it on web service. The message says some error occurred on GDI+.
I've searched on Google with some keywords C#, e-mail, and image. Many of the first searched results are teaching the way with attaching image with image file name. How can I e-mail to someone with image but no need to save it as a file?
What I have tried:
