Follow the CodeBank link in my signature and check out my thread on Saving Images To Databases. That thread demonstrates how to save an Image object to a byte array via a MemoryStream. Once you have a byte array, you can call Convert.ToBase64String to get a string that you can then feed to your QRCodeEncoder.

I asked in more forums it tell me that cannot encoded image . all you can do when encode image is to convert to link
and when scan also .

and he see to me when scan or decoded qr code his personal image
meaning it is possible to make that
so that what idea can do that

QR*codes are not very big so it seems reasonable that you wouldn't be able to save as much data as is required by*an image. If you still want to give it a try then you can do as I said but you may be disappointed. As for finding that*thread I mentioned, I'm here to help people learn how to program. If you can't use the web then you have some*work to do on your own first. You're just as capable*as me of clicking a link and reading a web page.

I've told you what to do. Now you need to do it. I don't need to watch any videos.
