Artifical Intelligence in c# ?

So , this is my program: https://www.dropbox.com/sh/16zmjqztltf17zy/jib9SL1H-J

The program is half ready, only need to finish the swapping ( can swap the lines each other )

My question is: There is any Artifical intelligence ( a* ; deep search, etc. ) algoritm in c# what i can use in this program ( So the program can solve itself )?

I saw some algorithm in java, but its not good in c#, clearly. :/

I really dont know how to continue with this, if someone who really know something about Artifical intelligence and good c# programmer, write some tips.

Thank You, Michael
