I have a long string of characters as input and I want to count the number of words in that string. How can I do it through regular expression?

Solution 1

Try:
 
            Regex word = new Regex(@"\w+");
            string data = "The quick brown fox jumps over the lazy dog.";
            Console.WriteLine(word.Matches(data).Count);
 
Get a copy of Expresso [^] - it's free, and it examines and generates Regular expressions.

Probably, but that's the one I use, because it works for me!

string[] Output=Input.Split(' ');
Console.WriteLine("No of Words in Given String is {0}",Output.Length.ToString());
