Extract domain with subdomain in side class

I have an ASP.NET 3.5 Web application with C# 2008.

What I need to do is, I want to extract full domain name in side a class method from Current URL.

For example :

I do have Current URL like : 

http://subdomain.domain.com/pagename.aspx

OR 

https://subdomain.domain.com/pagename.aspx?param=value&param2=value2

Then the result should be like, 

http://subdomain.domain.com

OR 

https://subdomain.domain.com

Create a Uri and query the Host property:

var uri = new Uri(str);
var host = uri.Host;

(Later)

I just realized that you want the scheme and the domain. In that case, @SLaks answer is the one you want. You could do it by combining the uri.Scheme and uri.Host, but that can get messy for things like mailto urls, etc.

You're looking for the Uri class:

new Uri(str).GetLeftPart(UriPartial.Authority)
