Back-end generation of QR code-C # generate two-dimensional code (QR)

Recently found a relatively good C # QR code generation Class library on GitHub. Here to share with you.

GitHub Address: Https://github.com/codebude/QRCoder

Download the solution, compile and generate QRCoder.dll, and you can use it. This class library has fewer parameters to customize, and only supports two parameters (two-dimensional code text, error correction level). Where the picture size is not good control, you can generate a larger picture. Limit the size of the picture when it is displayed at the front desk. (QR code image is enlarged to reduce, generally does not affect the recognition degree.) )

1 usingQrcoder;2 3 namespaceQrcodesample4 {5     class Program6     {7         Static voidMain (string[] args)8         {9             varText ="http://www.baidu.com";Ten             varQrimage ="qr.jpg"; One  A             varQrgenerator =Newqrcodegenerator (); -Qrcodegenerator.qrcode QRCode =Qrgenerator.createqrcode (text, qrcodegenerator.ecclevel.q); -              the             //You can modify this parameter to control the size of the picture.  -             varImage = Qrcode.getgraphic ( -); - image. Save (qrimage); -         } +     } -}

If you have a better class library, please do not hesitate to share.
