Split function in c#

I have a program which accepts a url(example:care.org), gets the page source of the url and does some calculation.

  string text = <the page source of care.org>
  string separator = "car";
  var cnt = text.ToLower().Split(separator,StringSplitOptions.None);

My aim is to count the number of occurence of the "car" in the page source, My code considers care as 'car'|'e' it splits it this way.. But i want it to consider whole seperator as one and do the splittin

Please help me with this

Solution

  • You should use reular expressions instead of split() method:

    Regex regex = new Regex(@"\bcar\b"); // you should modify it if `car's` needed

Match match = regex.Match(text);
int cnt = 0;

while (match.Success)
{
   cnt++;
   match = match.NextMatch();
}

// here you get count of `car` in `cnt`
