Currently I am trying to obtain the number of changed lines between two version of a source files, I currently do this by splitting the string I get from the Streamwriter.

        var rev1 = new DiffItemVersionedFile(versionControl, path, VersionSpec.ParseSingleSpec(latestVersion, null));
        var rev2 = new DiffItemVersionedFile(versionControl, path, VersionSpec.ParseSingleSpec(previousVersion, null));
        var stream = new MemoryStream();

        var writer = new StreamWriter(stream);
        {
            var options = new DiffOptions();

            options.Flags = DiffOptionFlags.EnablePreambleHandling;

            options.OutputType = DiffOutputType.Unified;
            options.TargetEncoding = Encoding.UTF8;
            options.SourceEncoding = Encoding.UTF8;
            options.StreamWriter = writer;
            Difference.DiffFiles(versionControl, rev1, rev2, options, path, true);

            writer.Flush();
            var diff = Encoding.UTF8.GetString(stream.ToArray());                
        }

That's what I'm currently obtaining from the Stream, formating looks a bit awkward, but there should be a more easy way to do this, since there usally is a structured object behind thats accesable.

  • You may want to have a look at [this answer](http://stackoverflow.com/questions/24887238/how-to-compare-two-rich-text-box-contents-and-highlight-the-characters-that-are/24970638?s=1|0.2731#24970638); it point to a very nice and powerful tool. Wrinting a good Diff is tough and not necessary. – TaW Feb 24 '15 at 10:28

  • I would like to determine the complexity of 2 versions of a source file, based on a few parameters one of them would be the lines of code changed. – joachim Feb 25 '15 at 09:00
