Please don't respond to questions that are either old or already accepted answers, as in this case. There are many other current questions waiting for help.

Yes, you can use Touchless SDK[^] for webcam and ZXing.NET[^] for QR code. They are both free and open-source.

You can also read the article 'WinForm Barcode Reader with Webcam and C#[^]' to learn how to implement a simple QR code reader using Touchless and a .NET barcode SDK.
