Remove all whitespace from C# string with regex -


i building string of last names separated hyphens. whitespace gets caught in there. need remove whitespace end result.

sample string work on:

anderson -reed-smith

it needs end (no space after anderson):

anderson-reed-smith

the last name string in string variable, lastname.

i using regular expression:

regex.replace(lastname, @"[\s+]", "");

the result of is:

anderson -reed-smith.

i tried:

regex.replace(lastname, @"\s+", "");

and

regex.replace(lastname, @"\s", "");

what doing wrong?

instead of regex use replace simple:

lastname = lastname.replace(" ", string.empty);
