zxing. NET multiple Barcode format generation

: http://zxingnet.codeplex.com/

Zxing.net is a tool for barcode and QR code under the. NET platform, which is very convenient to use.

This article mainly describes the generation of various types of bar codes.

Suitable for scenes, label visual design, custom barcode type, preview.

Traverse all barcode types supported by zxing
