Im having following reg-ex which is working OK, the only thing is if user type any value which is valid and press than spaces I got error, how can I avoid the space at the end of the values?
@"^[a-z\d][\da-z-.]*[a-z\s\d]$",

You want the regex to not match if there is a space just before the end? – donfuxx May 04 '14 at 15:29

Are a single "a" or "a." (for example) valid (with or without spaces at the end)? – Casimir et Hippolyte May 04 '14 at 15:51

^[a-z\d][\da-z-.]*[a-z\s\d][\s]*$
Use this if you want to accept any amount of whitespace characters at the end (small S).
^[a-z\d][\da-z-.]*[a-z\s\d][\S]*$
Use this if you don't want to accept strings with white spaces at the end (capital S).
Or you can also use the Trim function after you matched it with the unchanged regex.

Your second pattern is false, since `\S*` can match an empty string and `[a-z\s\d]` can match a space. – Casimir et Hippolyte May 04 '14 at 16:43

simply using
String.Trim();
string foo = " hello ";
string bar = foo.Trim();
Console.WriteLine(bar); // writes "hello"
