Winforms没有条形码支持。如果您已经使用库生成条形码，则可能会使用相同的库来解码条形码。无法解码所有条形码类型，因为专有条形码可能没有公开可用的规格。 

Winforms has no barcode support. If you are already using a library to generate barcode the same library probably can be used to decode barcode. It is not possible to decode all barcode types, as proprietary barcodes may not have specs openly available.
