Here you can find an C# implementation of the famous algorithm that finds the best diff of 2 inputs. You can use it for text documents and compare the complete lines, for a text lines and compare the characters or just to compare 2 arrays of numbers. This algorithm is used by many applications that need to find the best way to describe the difference e.g. to extract it as a patch.

This implementation is based on the algorithm published in "An O(ND) Difference Algorithm and its Variations" by Eugene Myers Algorithmica Vol. 1 No. 2, 1986, p 251.
