How do I replace multiple spaces with a single space in C#?

Question

How can I replace multiple spaces in a string with only one space in C#?

Example:

1 2 3  4    5 

would be:

1 2 3 4 5 

Answer 1

I like to use:

myString = Regex.Replace(myString, @"\s+", " "); 

Since it will catch runs of any kind of whitespace (e.g. tabs, newlines, etc.) and replace them with a single space.

Answer 2

string sentence = "This is a sentence with multiple    spaces"; RegexOptions options = RegexOptions.None; Regex regex = new Regex("[ ]{2,}", options);      sentence = regex.Replace(sentence, " ");
