I want to get count of the 'if' keywords in an input , i have wrote this code,but not working at all

string pattern = "if" + "\\B";

also

string pattern = "\\B" + "if" + "\\B";

What pattern should am I use ?

Define "not working at all" - what _does_ it do? What is different from your expectation? Why did you choose this pattern? — Oded, Feb 17 '12 at 19:53

Maybe this...

string sentence = "if abc if xyz"
string keyword = "if";
string pattern = @"\b" + Regex.Escape(keyword) + @"\b";
int count = Regex.Matches(sentence, pattern).Count

Hope it helps.
