Making simple database non mysql

[cwb2013]

I am very new to programming and I am working on a visual studio windows form app that will allow you to input information into 3 text boxes and then click a button to save that information to a simple file such as a .txt file, I need to also be able to enter information into one of those boxes and hit a search button and it will find that information such as a employee name or a customer etc, it would then populate those boxes with that particular information if it found a match in the .txt file. I was thinking I could do this with a struct but getting it store the information and retrieve the correct data is confusing me, any help would be appreciated.
