问题 I have a file server backup on an external hard drive a few months old for a file server that went down since then. Most of the data was recovered onto a temporary file server thats been in use since then but there are some inconsistencies.

You could as well save the left/right/ancestor files with the built-in

问题 Is there a c# library/algorithm that compares 2 texts and displays what is different in them? 回答1: See Diff.Net: Diff.NET is a differencing utility I wrote in C#. It provides side-by-side differencing for files and directories. For files it also provides an overview diff and a line-to-line diff. And it can do a visual difference of binary files. 来源： https://stackoverflow.com/questions/1509771/text-comparison-difference-algorithm
