title: How to add "using Zxing" in source code?
body: <p>I am new to c#. currently I am trying to decode qr code via webcam, I have taken an example from the internet and re written it to try to understand the code. my question is How do I add using Zxing instead of using <code>com.google.zxing</code>?</p>
  
  <p>I know that I should add a reference, but I try to add all the references I know but still it wouldnt allow me to add 'using Zxing'. it only allow 'using com.goggle.zxing' [ I use zxing.dll] as reference</p>
  
  <p>Another problem is compiler error at <code>var reader = new BarcodeReader();</code> I belief its related to the 'using Zxing" or unknown reference</p>
  
  <p>I really need help on this matter. Kindly show me how to solve or where can I find the Zxing reference. thanks again.</p>
