  maybe how about comparing the lines in both textboxesm, not the string.

  So what do the textboxes do Do they show the text, or just allow path input

  And ( again ), are these files text only

  TextReader tr1 = new StreamReader(path1);
  TextReader tr2 = new StreamReader(path2);

  string s1 = tr1.ReadToEnd();

  string s2 = tr2.ReadToEnd();

  bool areTheSame = (s1 == s2);

  The code I posted will tell you if they are different. Then the problem is, when you walk the strings and find a difference, you need to then step through both strings, trying to work out which has the extra text, or if both are containing unique strings and they are the same again further on.

  OK - that's a totally different question. You do need a richtextbox for this, because you want to show highlighting. This is a nontrivial problem and I'd be astounded if anyone wrote a diffing routine for you and posted it here.

  Either add them to the string, or write a custom control that renders line numbers to the left of the actual text being rendered. I'd go for option 2.

  You can split the string into an array of lines if you like, but that's not the way to go, and it doesn't solve any of the problem. You still don't know when you hit a difference if the two files are totally different from that point, if the first file has some extra info, if the second has some extra info, or if both have different info and then become the same again later on.

  What do you want to do Are the two files text only files Why do you want to use a richtextbox Do you want the code to compare the files, or the user If the code, why use rich text boxes

  *sigh* To reiterate:

  This is a nontrivial problem and I'd be astounded if anyone wrote a diffing routine for you and posted it here.

  using a path.. then it will be putted in the textboxes. If the button is clicked, it will highlight the differences.
