Regular expressions \b but with not just alphanumeric characters in c#

Question

I want the same functionality as \\b but with other characters.

In C#, I want to have something like

string str = \"\\\\b\" + Regex.Escape(         


        

Answer 1

For this you'd need a conditional word boundary at each end.
It just guards the string begin and end, if it's a word, it must be at
a word boundary.

If it's not a word, the default is nothing, as it should be.

 (?(?= \w )
      \b 
 )
 (?: @\(Something )
 (?(?<= \w )
      \b 
 )

So, it ends up looking like

string str = "(?(?=\\w)\\b)" + Regex.Escape(string) + "(?(?<=\\w)\\b)";

This takes the guesswork out of it.
