C#

am a new programmer, doin my final year project. I am to develop a CD database. The software developed should extract the details of an audio CD ( like album name, artist, genre, year released) and then transfer them to a database. I am using an access database.

so far i hv been able to get the attributes except the year. Also how do I prevent duplicate copies of cd data like the album, artist, etc.
pls help,only hv 2days left to deadline.
