Question

I am currently using this code to replace exact match. However this does not work, it also removed where the words appear in other words.

Example:

string pattern = "(?i)(flo)";
jobTitle = Regex.Replace("Florist of Vinyl Flowers of flo abc", pattern, string.Empty);

This is making the string :

orist of Vinyl owers

Which is wrong it should only remove flo from the string, and if I use :

string pattern = "(?i)\b(flo)\b";

It does not match however even if there is a complete word in there it wont match, nothing matches/

UPDATE :

The complete code runs like this:

splitter = wordToremoveTitle.Split('|');
if (splitter.Length > 0)
 {

  for (int t = 0; t < splitter.Length ; t++)
  {
  String pattern = @"(?i)\b(" + splitter[t] + ")\b";
  jobTitle = Regex.Replace(jobTitle, pattern, string.Empty);
  }

Answer 1

you was so close, regex: (?i)\bflo\b

string pattern = @"(?i)\bflo\b";
jobTitle = Regex.Replace("Florist of Vinyl Flowers", pattern, string.Empty);

if word mean “Florist” and “Flowers” but not “flo” use this one (?i)\b[^ ]*flo[^ ]*\b
