I have a string like this: MyUnsolvedProblem

I want to modify the string like this: My Unsolved Problem

How can I do that? I have tried using Regex with no luck!

Answer 1

var result = Regex.Replace("MyUnsolvedProblem", @"(\p{Lu})", " $1").TrimStart();

Without regex:

var s = "MyUnsolvedProblem";
var result = string.Concat(s.Select(c => char.IsUpper(c) ? " " + c.ToString() : c.ToString()))
    .TrimStart();

Answer 2

resultString = Regex.Replace("MyUnsolvedProblem", "([a-z])([A-Z])", "$1 $2");
