Remove whitespace within string

Question

I have strings like this:

"This______is_a____string."

(The "_" symbolizes spaces.)

I want to turn all the multiple spaces into only one. Are there any functions in C# that can do this?

Answer 1

var s = "This   is    a     string    with multiple    white   space";

Regex.Replace(s, @"\s+", " "); // "This is a string with multiple white space"

Answer 2

Regex r = new Regex(@"\s+");
string stripped = r.Replace("Too  many    spaces", " ");
