I have used the following code for spelling checking.While i am running that i am getting an exception--"

The code is:

using (Hunspell hunspell = new Hunspell("en_us.aff", "en_us.dic")) { bool correct = hunspell.Spell("Recommendation"); var suggestions = hunspell.Suggest("Recommendatio"); foreach (string suggestion in suggestions) { Console.WriteLine("Suggestion is: " + suggestion); } }

    // Hyphen 
    using (Hyphen hyphen = new Hyphen("hyph_en_us.dic")) 
    { 
        var hyphenated = hyphen.Hyphenate("Recommendation"); 
    } 

• using (MyThes thes = new MyThes("th_en_us_new.idx", "th_en_us_new.dat")) { using (Hunspell hunspell = new Hunspell("en_us.aff", "en_us.dic")) { ThesResult tr = thes.Lookup("cars", hunspell); foreach (ThesMeaning meaning in tr.Meanings) { Console.WriteLine(" Meaning: " + meaning.Description); foreach (string synonym in meaning.Synonyms) { Console.WriteLine(" Synonym: " + synonym);

              } 
          } 
      }
