I run a forum and I want to automatically replace any link to a YouTube video with a iframe youtube video player using ASP.NET+C#.

How to replace this Link

<http://youtu.be/uN-A8eHte1g>

with

```
<iframe class="youtube-player" frameborder="0" height="250" src="http://www.youtube.com/embed/uN-A8eHte1g?rel=0&amp;wmode=Opaque" title="YouTube video player" type="text/html" width="100%"></iframe>

```

I can't really find anything like this on the ineternet.

Hope someone could help me this. Thanks in advance!
