String search and count

Mark P. · July 22nd, 2011, 06:36 PM

Quick question. Is there a way to search a string and return the number of matches? Example, the string is "kkllkjhgfklkjjj" and the code would return the number of k's.

Mark, as a string is just a collection of characters you can use LINQ to filter the string any way you want:

Code:

var count = (from c in s
                   where c == 'k'
                   select c).Count();
