.NET Library for merging files

Question

Hi all, Do You know any .net library that can be used for comparing and especially merging of two files (like .pst) - would be the best if open-source or inexpensive.

Answer 1

Here are some implementations

• http://www.codeproject.com/KB/recipes/diffengine.aspx
  • written some time ago but is entirely public domain
• http://www.mathertel.de/Diff/
  • Based on Eugene Myers classic algorithm. currently BSD licensed
  • Also old but the algorithm and implementation are well established and stable
• http://www.menees.com/DiffDotNet.htm
  • as an application, though it defers almost all the diff logic to a simple library so would be a good example of the libraries use.

I would suggest starting with the Myers implementation since it is based on a well reasoned algorithm and so if there is a bug you are likely to be able to identify it against some other reference implementation.
