Getting the end of a domain name

[Adam Tibi]

Hello,

I want to get the right most name of the a domain name, for example:

if the domain is www.myweb.com , I want to get myweb.com
something.myweb.com --> myweb.com
www.myweb.com.au --> myweb.com.au
something.myweb.com.au --> myweb.com.au
www.myweb.tv --> myweb.tv
www.something.myweb.net --> myweb.net
my.test.myweb.ca --> myweb.ca

I want to know if there is a general rule, code or article regarding this
issue.
I tried the following code, but I am not convinced, because it is not
generic
public static string GetDomainName(string serverName ) {

if(!serverName.Contains(".")) {

return serverName.ToLower();

}

if(serverName.EndsWith(".co.uk")) {

return serverName.Substring(serverName.LastIndexOf(".", serverName.Length -
".co.uk".Length - 1) + 1).ToLower();

}

if(serverName.EndsWith(".com") || serverName.EndsWith(".net") ||
serverName.EndsWith(".org")) {

return serverName.Substring(serverName.LastIndexOf(".", serverName.Length -
5) + 1).ToLower();

}

return null;

}

Does any one have a better solution?

Adam,
I'd take a look at the System.Uri class, which has some built-in properties
that simplify segmenting out the portions of a Uri. There may be additional
ways to do it that I'm not aware of.

Hi,

Save your primary domain name (myweb) globally. Get the host name with HTTP_HOST server variable and use substring function

e.g.

string tct = @"www.something.myweb.net.au";
MessageBox.Show(tct.Substring(tct.IndexOf("myweb") ));

Will display out as myweb.net.au

Hope this might help you...

Thank you Vinu,

The problem here is that I don't know the domain name in advance, I am going to get different domain names and I need to parse them, so this solution doesn't work because it assumes that I know the domain name in advance. I want a global solution that will get the last portion of any domain name.

ideas any one?

As Peter tried to convey, there's probably a method in a class the framework
provides. The "long hand" way I did this in ASP can still be done using
ASP.NET...

* Get the URL as a string and trim white space from front and back
* Pass the trimmed string to a string reverse method
* Split the reversed string on the . character
* Get the value from the [0]th array indice
* Reverse that value and you get "com", "org", "aero", "name" or whatever

Note when we split a string an array is created. Simply get the value from
the [0]th indice as I indicate and reverse the value and you get what you
want.

Thank you Clinton,

You are assuming that the extention is just one part like "org" or "net" but
it might be "com.au" or "co.uk" and I currently made a solution for the
extentions that I know but I wanted a generic solution that doesn't require
me to check .com.au, .com.lb, .co.uk, ca, net, org, us, info, etc...

I just wanted a general rule for this.
