C# HTML Stripping

Question

Hello C# Corner

Currecntly I am trying to strip some html tags using this regex:
<[^>]*(>|$)|&nbsp;|&zwnj;|&raquo;|&laquo;

However I still end up with signs as { font-size:9pt; font-family: arial; }

So basicly I want the styling gone aswell,

 

How can I strip { } aswell?

Best regards
