为什么在问这个简单问题之前不进行搜索?

读取条形码扫描器-Codeproject搜索 [ ^ ]

Why didn''t you search before asking this simple question?

Read Barcode Scanner - Codeproject Search[^]

您需要至少有条码读取器SDK才能执行此操作.我认为每个条形码阅读器都附带其SDK.查看手册.

You need to have atleast a barcode reader SDK to do this. I think every barcode reader comes with its SDK. Check the manual.
