I also uploaded the Silverlight port of the ZXing library to http://silverlightzxing.codeplex.com/. The project includes sample code for using the library as well as a BarcodePhotoChooser XAML/CS page for displaying and choosing sample barcodes since the emulator does not support the camera. I plan on submitting bug fixes and additional code to this project so that others can also use it in their Windows Phone 7 or Silverlight applications.
Microsoft probably won't develop this capability since it can readily be provided by 3rd Party SDKs and there is fairly health barcode expertise out there in the community already.
There are several applications in the marketplace having this feature, maybe one of them list the component used to read the barcodes: http://wp7applist.com/search/?q=barcode

我编写了前面提到的 PhraseMeme Scanner 应用程序，是的，它基于 ZXing 库。该应用程序现已发布到市场，更多信息请访问http://PhraseMeme.com/Scanner
我还将 ZXing 库的 Silverlight 端口上传到 http://silverlightzxing.codeplex.com/。该项目包括使用该库的示例代码以及用于显示和选择示例条形码的 BarcodePhotoChooser XAML/CS 页面，因为模拟器不支持相机。我计划向该项目提交错误修复和附加代码，以便其他人也可以在他们的 Windows Phone 7 或 Silverlight 应用程序中使用它。
I wrote the PhraseMeme Scanner app that was mentioned, and yes it is based on the ZXing library. The app has now been released to the marketplace, and more information can be found at http://PhraseMeme.com/Scanner

WP7 SDK 没有内置从图像中读取条形码的功能。
不过，SDK 确实具有使用 CameraCaptureTask 拍摄照片的功能。这里有一个执行此操作的示例。
如何：使用 Windows Phone 启动器
此外，您还可以查看网上的 .net 项目，该项目提供了从提供的图像中读取条形码的功能。例如..
从图像中读取条形码
Microsoft 可能不会开发此功能因为它可以很容易地由第三方 SDK 提供，并且社区中已经有相当多的健康条形码专业知识。
The WP7 SDK does not have the capability built in to read a barcode from an image.
The SDK does have the capability to take the picture though, using CameraCaptureTask.. there is a sample for doing this here.
How to: Use Launchers for Windows Phone
Also, you could take a look at .net projects on the net that offer the capability to read a barcode form a supplied image. For example..
Reading Barcodes from an Image
Microsoft probably won't develop this capability since it can readily be provided by 3rd Party SDKs and there is fairly health barcode expertise out there in the community already.
市场上有多种应用程序具有此功能，其中之一可能列出了用于读取条形码的组件：

有一个 C# 版本的 ZXing来自 Google 的与 Windows Phone 7 兼容的：

更新此应用程序似乎使用 ZXing 并将发布其代码：

Update this app seems to use ZXing and will release their code:
