XML and C#

Question

Hi, I want to make a simple console application in C# using XML. What I want it to do is: -check to see if the XML file exists. If it does, retreive the info from it. If it doesn't, create it. -be able to display the info in the XML file. -be able to modify, add or delete entries The info in the XML file is simple, I'm just doing this for both fun and convenience: what I want to put in the XML file is a list of all my comic books with series name, title, author, number, ISBN and publisher. I've been looking around a little but some things I have tried have not worked. Can someone give me a hand or point out a tutorial or something. Thanks for your time!
