Split a string by capital letters [duplicate]

Question

Regular expression, split string by capital letter but ignore TLA

I have a string which is a combination of several words, each word is capitalized.
For example: SeveralWordsString

Using C#, how do I split the string into "Several Words String" in a smart way?

Thanks!

Use this regex (I forgot from which stackoverflow answer I sourced it, will search it now):

 public static string ToLowercaseNamingConvention(this string s, bool toLowercase)         {             if (toLowercase)             {                 var r = new Regex(@"                 (?<=[A-Z])(?=[A-Z][a-z]) |                  (?<=[^A-Z])(?=[A-Z]) |                  (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);                  return r.Replace(s, "_").ToLower();             }             else                 return s;         }

[EDIT]

I found it now: How do I convert CamelCase into human-readable names in Java?

Nicely split "TodayILiveInTheUSAWithSimon", no space on front of " Today":

using System; using System.Text.RegularExpressions;  namespace TestSplit {     class MainClass     {         public static void Main (string[] args)         {             Console.WriteLine ("Hello World!");                var r = new Regex(@"                 (?<=[A-Z])(?=[A-Z][a-z]) |                  (?<=[^A-Z])(?=[A-Z]) |                  (?<=[A-Za-z])(?=[^A-Za-z])", RegexOptions.IgnorePatternWhitespace);               string s = "TodayILiveInTheUSAWithSimon";             Console.WriteLine( "YYY{0}ZZZ", r.Replace(s, " "));         }     } } 

Output:

 YYYToday I Live In The USA With SimonZZZ
