Library for reading QR codes using a webcam

I am looking for an open source library that can read QR codes using the built-in webcam for a laptop.

Preferably, the library should be written in C #, but Java would be good too. It should run on a 64-bit Windows 7 platform.

It is important that I have access to the decoded string, i.e. I do not want the application to open the URL in the browser. I looked around and found libraries that either read codes from image files, or use a webcam for input, but do not allow access to the line. I was not able to find one that does what I want. Any pointers would be appreciated.

Thank you for your help and suggestions.

ZXing / Zebra Crossing is the software library that is located behind the most popular QR-reading Android application called Barcode Scanner .

The core library is licensed under Apache License 2.0 and is reliable for low-quality inputs (such as webcams) and provides decoded content and allows you to decide how to use it.
