How can I get domain name without WWW in C# or VB.Net

Question

I want to get domain name without the "http" and "www".

For example:

 https://www.google.com => google.com

 http://www.google.com => google.com

 www.google.com => google.com

Attempts made:

               Dim myUri As New Uri(url)
                Dim host = myUri.Host
                Dim host1 = myUri.AbsolutePath
                Dim host2 = myUri.AbsoluteUri
                Dim host3 = myUri.Authority
                Dim host4 = myUri.DnsSafeHost
                Dim host5 = myUri.Fragment
                Dim host6 = myUri.HostNameType

None of this works for me. Can some one guide me how to achieve above in C# or VB.Net (preferrable VB.Net)

Do you want to exclude all sorts of subdomains (eg. codereview.stackexchange.com => stackexchange.com) or just www? — bl4y., Mar 20 '17 at 20:15

The closest you can get is through the Uri.Host property. After that you need to use string manipulation like:

myUri.Replace("www.", "")

Won't work if the site is something like www.testwww.com or www3.test.com – Zun Dec 19 '21 at 12:52
