Searching List <dvd> C # : I have a DVD Rental application. And in my Store.cs (class) i need to search the Dvd.cs (class) for un rented dvds and save the film from the Movie.cs class in results in a list (getAvailableDVD). 
Movie.cs has properties set & a List<dvd> & in my Dvd.cs i have an enum for availability {Available,Rented,Not Available}

im quite new to this idea, but im wanting to search the list for each Availability.Available and return its corresponding film(movie.cs)

anyone have ideas on how to approach a search method in my Store.cs?
