An array containing an array and simple types?

[Dave Griffiths]

Hi all,

I'm banging my head over this one but there's got to be an easy answer!
I have a library of books. Each book has simple types: string sTitle, string sAuthor, boolean bIsHardback
but a book also has a number of pages. A page must exist(there may be >1) and pages need a number of simple types: string sPageText, boolean bHasImage.

My logic says this works:

class APage
    {  // A single page
        public boolean bHasImages;
        public string sPageText;
    }
    class ABook
    {   // Object to hold pages 
        string sTitle;
        string sAuthor;
        boolean bIsHardback;
        APage[] BookPages;
    }
 

When I try this, I can't work out how to initialise the inner array (APages). I've tried

APage()
{
APage[]=new APage[1];
}

as initialiser in the APage class but clearly, I'm missing something obvious. Can anyone help an ex-Pascal guy get his head around this? ;-)

You're close!

APage()
{
  BookPages = new APage[1];
}

Looks like a bit of a typo... long day? Been there :)

If your book is intended to have any number of pages, might I recommend using a list instead?

List<APage> BookPages = new List<APages>();

It's a little easier to work with in my opinion.

Doh! Do I feel stoopid right now ;-)
Thanks for spending the time on something so very trivial, Gary!
Like the idea of the List - thanks for the heads-up on that one.
