You can find a demo WindowsForms application, which show encoding and decoding from a webcam in the source-code on codeplex:
您可以在 codeplex 的源代码中找到一个演示 WindowsForms 应用程序，它显示了来自网络摄像头的编码和解码：

I've never done this, but with a little research I can suggest this:
我从来没有这样做过，但是通过一些研究，我可以提出以下建议：
Check thisarticle - it has a working example of how to get a stream from a USB camera. It's not simple, but it is worth trying :)
On this page: http://zxingnet.codeplex.com/scroll to the Usage Example. Over there I can see that it accepts a bitmap and then returns a result or a null if it can't recognize the barcode. So, all you need to do from #1 is to convert the stream to a bitmap object and pass it to zxing barcode reader.
zxing.NET returns the decoded number in plain text, so you can output it to the screen on any way you want?
检查这篇文章 - 它有一个关于如何从 USB 摄像头获取流的工作示例。这并不简单，但值得一试:)
在此页面上：http: //zxingnet.codeplex.com/滚动到使用示例。在那里，我可以看到它接受位图，然后如果无法识别条形码，则返回结果或空值。因此，从 #1 开始，您需要做的就是将流转换为位图对象并将其传递给 zxing 条形码阅读器。
zxing.NET 以纯文本形式返回解码后的数字，因此您可以以任何方式将其输出到屏幕上？
Any reason not to use a barcode reader device?
有什么理由不使用条形码阅读器设备？
