Sure we can. Here's some revised code: using System; using System.Linq; using System.Text.RegularExpressions; using System.IO; class Test { static void Main() { Console.Write(Please enter file name to analyze : ); string fileName = Console.ReadLine(); string text = null; try { text = File.ReadAllText(fileName); } catch(IOException ex) { Console.WriteLine(ex.Message); return; } Console.WriteLine(); MatchCollection mc = Regex.Matches(text @\b\w+\b); var query = from Match m in mc group m by m.Value.ToLower() into g select new {Word = g.Key Frequency = g.Count()}; foreach(var item in query) { Console.WriteLine({0} : {1} item.Word item.Frequency); } Console.ReadKey(); } }

In principle you can count the words in a piece of text using C# and LINQ as follows: using System; using System.Linq; using System.Text.RegularExpressions; class Test { static void Main() { string text = The quick brown fox jumps over the quick lazy dog and the quick brown cat; MatchCollection mc = Regex.Matches(text @\b\w+\b); var query = from Match m in mc group m by m.Value.ToLower() into g select new {Word = g.Key Frequency = g.Count()}; foreach(var item in query) { Console.WriteLine({0} : {1} item.Word item.Frequency); } Console.ReadKey(); } } A 'word' for this purpose can only consist of the characters: a-z A-Z 0-9 or underscore but can be easily changed to include other characters. The output of the above program should be: the : 3 quick : 3 brown : 2 fox : 1 jumps : 1 over : 1 lazy : 1 dog : 1 and : 1 cat : 1
