Posted

The code for the same is:

-Downdload DLL here
-include reference:

C#
using MessagingToolkit.QRCode.Codec;
using MessagingToolkit.QRCode.Codec.Data;

to generate barcode from image:

C#
string url = textBox1.Text;/*textbox string is converted to qrcode*/
            QRCodeEncoder enc = new QRCodeEncoder();
            Bitmap qrcode = enc.Encode(url);
            pictureBox1.Image = qrcode as Image;


and to decode

C#
QRCodeDecoder dec = new QRCodeDecoder();
textBox2.Text = (dec.decode(new QRCodeBitmapImage(pictureBox1.Image as Bitmap)));/*qrcode is reverted back to string*/
