C# compare algorithms

Question

Are there any open source algorithms in c# that solve the problem of creating a difference between two text files?

It would be super cool if it had some way of highlighting what exact areas where changed in the text document also.

There's also a c# port of Google's (Neil Fraser) diff, match and patch.

There is Menees Diff which will provide you with a C# diff implementation. The source code is included. I've used it in the past with good success wrapping it in my own implemenation.

Check out diff. Here it is in the gnu project (open source, of course), and many more links to implementations are found in the wikipedia article. A comparison of different such programs is found here.
