  Regex Meets Linq
  OmegaMan Wednesday, February 4, 2009 5:16 PM

  If you love Regex...then Regex and Linq is a match made in Heaven. Here are two scenarios where Regex and linq can be used together.
  
  

  • Place Key Value Pairs into a dictionary<string,string> object from regex: Regex To Linq to Dictionary in C#

  
  
  Here is a quick example where this input "123abcd3" will tokenized into digits or characters and placed into an IEnumerable array with values of "123", "abcd" and "3".
  
  The tokenization will occur and the named match Tokens will contain sub captures. Those captures will be enumerated and placed into an IEnumerable <string> array.
  
  

  string input = "123abcd3";

  string pattern = @"(?<Tokens>\d+|[a-zA-Z]+)+";

  var items = from Match m in Regex.Matches( input, pattern )

  from Capture cpt in m.Groups["Tokens"].Captures

  select cpt.Value;

  Console.WriteLine( string.Join( ",", items.ToArray() ) );

  // Outputs

  // 123,abcd,3

  
  
  
  
  
  This should get you started in using Linq with Regex. GL HTH
