string comparison

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.

Answer 1

Give a look to the following libraries:

• A Generic, Reusable Diff Algorithm
• An O(ND) Difference Algorithm for C#
• Diff/Merge/Patch Library for C#/.NET
• Diff.NET
