Use chrome as browser in C#?

You can use GeckoFX to embed firefox

I use Awesomium, I think it is better than GeckoFX/WebKit http://awesomium.com

I don't know of any full Chrome component, but you could use WebKit, which is the rendering engine that Chrome uses. The Mono project made WebKit Sharp, which might work for you.

You can use WebKit.NET. This is a C# wrapper for WebKit, which is the rendering engine used by Chrome.
