Regex for removing extra whitespace

[Ray Stevens]

Does anyone know of a Regex expression from removing extra whitespace within
a string (such as 5 spaces instead of 1, etc.)?

search for "\s+"and replace it with " "

solution? Is there any other way can do it faster?

I don't know about faster, but you could also:

string s = "1 3 6 0";
while (s.Contains(" ")) s.Replace(" ", " ");
^^ ^^ ^

But of course, that only counts spaces... If you want to get rid of other
whitespace, you'll have to account for that. Really, there's no reason
NOT to use the regular expressions.
