Extension Method: Get total Word Count of a string

Using regular expression and Extension Method in C#, code below provides a simple way to count all words to a given string excluding all whitespaces, tabs and line breaks.

   1: using System.Text.RegularExpressions;

   2:  

   3: public class MyExtension

   4: {

   5:     /// <summary>

   6:     /// Count all word occurrence

   7:     /// </summary>

   8:     /// <param name="input">string to begin with</param>

   9:     /// <returns>int</returns>

  10:     public static int WordCount(this string input)

  11:     {

  12:         var count = 0;

  13:         try

  14:         {

  15:             // Exclude whitespaces, Tabs and line breaks

  16:             var re = new Regex(@"[^\s]+");

  17:             var matches = re.Matches(input);

  18:             count = matches.Count;

  19:         }

  20:         catch

  21:         {

  22:         }

  23:         return count;

  24:     }

  25: }

and we could use this code like this:

   1: string word = "the quick brown\r\nfox    jumps over the lazy \tdog.";

   2: Console.WriteLine("Total Words: {0}", word.WordCount());

   3: // Output: Total Words: 9

The code is also posted in Extension Method website.
