Question

I am horrible with Regex stuff. I would like to use a regular expression in C# to turn any two or more spaces into non-breaking spaces. I would like to leave single spaces alone.

You can use a MatchEvaluator as the replacement argument. In C# 3.0 or newer you can use a lambda function:

s = Regex.Replace(s, " {2,}", x => x.Value.Replace(" ", " "));
