推荐答案
如何执行条形码扫描
这取决于您的设置，硬件，毛边。要么它像键盘输入，要么通过串口获得。在任何情况下，你最终都会得到一个字符串。
It depend on your settings, hardware, frovers. Either it is like a keyboard entry, either you get it via serial port. In any cases you end up with a string.
并根据条形码扫描来检索/获取数据数据库
and retrive/ fetch data based on barcode scan from database
使用你所拥有的字符串，你可以像往常一样，这里没什么特别的。
With the string you have got, you do exactly as you usually do, nothing special here.
你的.net代码在服务器上运行，无法访问客户端硬件。这仅适用于您使用的扫描仪带有允许从浏览器使用的软件插件.hp的插件。请联系该扫描仪制造商，了解是否支持此功能。
Your .net code runs on the server and has no access to client hardware. This will only work if the scanner you use comes with software\plug-ins that allows it to be used from a browser. Contact that scanner manufacturer to see if this is supported.
