Adding some inputs into a <List>

I can manage to get this to work with the top class but when I have lower classes I dont get this to work.

I want a list to be printet out in a listbox. Like this:

Die hard    Date     Distributor      Category

but all the code includes is the thing from class movie and not audioVideo
this wont come out
        private string m_country;
        private string m_language;
        private decimal  m_price;
        private DateTime m_releaseDate;
        private int m_runtime;
        private string m_title;

this willl

        private string m_category;        
        private string m_system;
        private string m_distributor;

See code


List<AudioVideo> audioVideoLista = new List<AudioVideo>();
List<Movie> movieVideoLista = new List<Movie>();

If I understand your meaning, when you use List<Movie> movieVideoLista as the datasource for the listbox, the text displayed in the listbox isn't what you expect.

I think you wanted to be able to access m_title, m_releaseDate in the class Movie, but these are marked as private in AudioVideo, so they can't be accessed. You could always declare them as protected, but I wouldn't recommend it.

Apologies if this is not what you wanted.
public override string ToString() {
  //return "" + m_category + "_!_" + m_distributor + "_!_" + m_system + "_!_";
  return this.Title + "_!_" + this.Date + "_!_" + this.Distributor + "_!_" +
    this.Category + "_!_";
} //end ToString

but I thought they should be private. I use the get and set to access them.

The code you wrote is that in the top class AudioVideo
or the lower Movie.

The code I wrote would replace public override string ToString() in Movie.
You're absolutely correct, I would have done the same and made m_title private. The only reason I suggested using Protected is because I thought you may have been trying to access m_title from Movie.ToString()
