C # generate a bar code Image

On the Internet, I can see that some people write code on the bar code for a long time, and some even sell it. So I checked the information and hoped to help you.

 

My implementation principle is:

In fact, Windows itself has a font used to display the bar code.

You only need to change the number to this font to a bar code.

 

In the windows Font Library, there are eight types of fonts that can be used to convert numbers into barcode:

Code39AzaleaNarrow1

Code39AzaleaNarrow2

Code39AzaleaNarrow3

Code39AzaleaRegular1

Code39AzaleaRegular2

Code39AzaleaWide1

Code39AzaleaWide2

Code39AzaleaWide3

 

Post the code for your reference:

Bitmap B = new Bitmap (200,200 );

Graphics g = Graphics. FromImage (B );

Font font = new Font ("Code39AzaleaRegular2", 32 );

G. DrawString ("123456", font, Brushes. Black, new PointF (100,100 ));

PictureBox1.BackgroundImage = B;

PictureBox1.BackgroundImageLayout = ImageLayout. Zoom;
