Getting the domain from a URL encoded string

Question

Another beginner question, I'm afraid...

I was wondering if someone could tell me the easiest and most efficient way of getting the fully qualified domain name (e.g. www.google.com) from a UrlEncoded string in ASP.Net (C#).

For example:

 http%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3Dsome%20things%20i%20searched%20for

Would give me:

 www.google.com

(Or basically anything where I can check the domain to make sure it's correct.)

I'm guessing the first step might be to UrlDecode, but since this is how I'm getting the string, I thought I'd mention it incase it's easier Encoded.

Thanks for any help!

(new URI(System.Web.HttpServerUtility.UrlDecode(url))).Host

For reference:

Every now and then I type new Url( xxx ) and get surprised it's not what I want.

I believe you can use Request.Url.host to get the hostname.
