You (probably) will not have a barcode scanner into your server, but on user computers.
您（可能）不会在您的服务器上安装条形码扫描仪，而是在用户计算机上安装。
A barcode scanner typically reads a barcode, understand it, and to make that read data to be understood by your computer as entered by keyboard. So you'll just need to send that data to server to be processed.
条码扫描器通常读取条码，理解它，并使计算机能够理解键盘输入的读取数据。所以你只需要将该数据发送到服务器进行处理。
EDIT:I don't have experience on reading barcodes, by you can look into this link to find how to create them: C# Barcode Generator WebService. Maybe you should buy one component for both tasks.
编辑：我没有阅读条形码的经验，您可以查看此链接以了解如何创建它们：C# Barcode Generator WebService。也许您应该为这两项任务购买一个组件。

If you need the barcode written into a textbox, you'll not need extra work to do. Barcode scanners simulate keypress event. Even you can handle window.keypress event to hook the preamble and postamble characters. That way the client do not need to focus on the specific textbox.
如果您需要将条码写入文本框，则无需额外工作。条码扫描器模拟按键事件。即使您可以处理 window.keypress 事件来挂钩前导和后导字符。这样客户端就不需要关注特定的文本框。
Or else the reader uses a hardware driver (? don't know such vendors exists ?) , then you'll need an ActiveX object to wrap the library.
或者读者使用硬件驱动程序（？不知道这样的供应商存在吗？），那么您将需要一个 ActiveX 对象来包装库。
