@"^[a-z\d][\da-z-.]*[a-z\s\d]$",

^[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.

simply using

String.Trim();

 string foo = "   hello ";
 string bar = foo.Trim();

 Console.WriteLine(bar); // writes "hello"
