大多数条形码扫描仪的行为与键盘完全相同，它们在前台应用程序中聚焦的任何字段中输入条形码文本。



如果没有关于您正在使用什么类型的条形码扫描仪或什么类型的应用程序（WinForms，WPF，ASP等）的更多信息，我们将无法提供太多帮助。

HI. sir
actually sir im developing management system in c#. i want to attach barcode scanner with my project so that i can scan any item through it.
Please sir help me about this, with the help of Example code
Thank you.

Most bar code scanners act exactly like a keyboard, they enter the bar code text in whatever field is focused in the foreground application.

Without more information about what type of bar code scanner you are using, or what type of application (WinForms, WPF, ASP, etc) we can't be of much help.
