                    MessagingToolkit.QRCode.Codec.QRCodeEncoder encoder = new MessagingToolkit.QRCode.Codec.QRCodeEncoder();
                    encoder.QRCodeScale = 8;
                    Bitmap bmp = encoder.Encode(textBox1.Text);

Creating a class:
public class QRCodeEncoderDemo
public static System.Drawing.Bitmap CombinImage(System.Drawing.Bitmap bit,string destImg)
System.Drawing.Image img = System.Drawing.Image.FromFile(destImg);

if (img.Height != 45 || img.Width != 45)


img = KiResizeImage(img, 45, 45, 0);


Graphics g = Graphics.FromImage(bit);
g.DrawImage(bit, 0, 0, bit.Width, bit.Height);
g.DrawImage(img, bit.Width / 2 - img.Width / 2, bit.Width / 2 - img.Width / 2, img.Width, img.Height);


return bit;

public static System.Drawing.Image KiResizeImage(System.Drawing.Image bmp, int newW, int newH, int Mode)
System.Drawing.Image b = new Bitmap(newW, newH);
Graphics g = Graphics.FromImage(b);
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.DrawImage(bmp, new System.Drawing.Rectangle(0, 0, newW, newH), new System.Drawing.Rectangle(0, 0, bmp.Width, bmp.Height), GraphicsUnit.Pixel);
return b;

return null;


internal System.Drawing.Image GCode(object p)
throw new NotImplementedException();

Using the class:
bitmap = encoder.Encode(textQr.Text);
bitmap = QRCodeEncoderDemo.CombinImage(bitmap, fileName);

An unformatted, unexplained code-dump is not a good solution to any question - especially not when the question was asked 5½ years ago!

Edit your solution. Format the code. Add an explanation of what you are doing, and how it solves the question.

Without that, your solution is likely to be removed.
