You should put all your words into some kind of Collection or List and then call it like this   var searchFor   new List lt string gt     searchFor Add  pineapple    searchFor Add  mango     bool containsAnySearchString   searchFor Any word   gt  compareString Contains word      If you need to make a case or culture independent search you should call it like this   bool containsAnySearchString       searchFor Any word   gt  compareString IndexOf       word  StringComparison InvariantCultureIgnoreCase  gt   0
