    QRCodeGenerator qrGenerator = new QRCodeGenerator();
    QRCodeData qrCodeData = qrGenerator.CreateQrCode(generator.ToString(), QRCodeGenerator.ECCLevel.Q);
    QRCode qrCode = new QRCode(qrCodeData);
    using (Bitmap bitMap = qrCode.GetGraphic(4))
    {
        using (MemoryStream ms = new MemoryStream())
        {
            bitMap.Save(ms, ImageFormat.Png);
            pictureBox1.Height = 300;
            pictureBox1.Width = 300;
            pictureBox1.Image = Image.FromStream(ms);
