Don't bump your question, it's rude.
Additionally, if you bump it by posting "Thank U" as a solution it removes it from the unanswered list and makes it less likely to ever get an answer...

I doubt the examples to be correct because "www.codeproject.com" isn't even present in "t.news.codeproject.com".

Are you sure you want the result to start with "www" by all means?

yes, I made mistake. BUT use the uri class I just get the sub level domain for above 2~4 example

then I must do something with the string ? cut the string or replace the substring before the first dot with "www"

For the four example Uris you have given, the top level domain for the first three is 'com' and for the last it is 'cn' and I do not think that this is really what you want.

Therefore please do some research into the names of the various parts of a uri/url and edit your question to indicate what you really want.
