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?

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

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

Here's a nice way without regex. With Linq.
var astring = "This is a string with to many spaces.";
astring = string.Join(" ", astring.Split(' ').Where(m => m != string.Empty));
output "This is a string with to many spaces"

You can also use StringSplitOptions.RemoveEmptyEntries on the astring.Split() call to remove your Where filter.
The regex examples on this page are probably good but here is a solution without regex:
string myString = "This is a string.";
string myNewString = "";
char previousChar = ' ';
foreach(char c in myString)
{
if (!(previousChar == ' ' && c == ' '))
myNewString += c;
previousChar = c;
}

@David Agree, there are optimalisations to make, but using a
StringBuilder, or the like, would have made my example more difficult to understand. Giving myNewString and previousChar an initial value is also not optimised, but I'm merely trying to make a suggestion as to how to approach the issue without regex. Feel free to make it "perfect" :)
