Select a HostName with Regex in C# ?

[tonyonlinux]

^(ftp|http|file)://([^/]+)(/.*)?(/.*)

so

http :// www.codeproject.com /forum /xxx.html
1 2 3 4

so the reg expression would spit out $1 = http $2 = www.codeproject.com $3 = /forum $4 = /xxx.html hope this helps.

Try this instead of a Regex:

MessageBox.Show((new Uri("http://rs320tl.rapidshare.com/files/119371167/sth.rar")).Host);

I didn't know that a Uri broke it down for you - thanks for that!:thumbsup:

I think you mean Uri. It's in the System namespace.

Thanks, How can I store $2 in a string?

Try this:

MessageBox.Show((new UriBuilder("rs320tl.rapidshare.com")).Host);
