推荐答案

您的条形码扫描仪应支持将条形码作为文本转储.这不是编程问题，它是硬件问题，请阅读扫描仪的手册.

但是我需要将从条形码获得的数字保存在数据库中"

好，那是一个不同的问题.这只是一个数字.以与其他任何字符串一样的方式进行存储(我怀疑它太长了，无法存储为数值)

Your barcode scanner should support dumping the barcode as text. This is not a programming question, it''s a hardware question, read the manual of your scanner.

"but i need to save the number that got from barcode in database "

OK, that''s a different question. It''s just a number. Store it the way you would any other string ( I suspect it''s too long to store as a numeric value )
