    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 .
    but before two days i some customer request from me to make qr code encode and decode personal image
    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.
