How do I store both objects and ints in an array?-CodePudding

I'm currently working on a project where I have to transform a warehouse into an array representation, however, I am running into a problem. I want to define the path where the workers can walk as an arraycell with a value = 1. Places, where the workers can't go, will have a value of 0, and the shelves with items will be Object. This is of course not a viable option, as we can't store objects in an int array, however, I currently can't think of another way to represent pathways other than using int arrays. So how would one go about doing this? Here's a quick visual representation of what I'm looking for: Array example

namespace MyApplication
{
    
  class MagazijnObject
  {
    public string Locatie;//waar ligt het product?
    public int Ranking; //hoe populair is dit product?
    public string Item; //welk product ligt hier?

    
    public MagazijnObject(string loc, int rank, string it)
    {
     Locatie = loc;
     Ranking = rank;
     Item = it;
    }
     

    static void Main(string[] args)
    {
      MagazijnObject voorbeeld = new MagazijnObject("D02020A", 1, "Meel");
      Console.WriteLine(voorbeeld.Locatie);
      Console.WriteLine(voorbeeld.Ranking);
      Console.WriteLine(voorbeeld.Item);
      int[,] GangVoorbeeld = new int[5,10]; //this is a single hallway, with shelves on either side
      string gang = "D02";
//traverse array
      for (int i = 0; i < GangVoorbeeld.GetLength(0); i  )
      {for (int j = 0; j < GangVoorbeeld.GetLength(1); j  )

      { if ( i == 1 || i == 3) //shelves with items
      {GangVoorbeeld[i,j] = new MagazijnObject(gang   i, 1, "test"); //try to create object, however can't do so because I have an int array. However, I don't know how to define the walking path in an object representation.
      }
      
      }
      
      
    }
  }
}}

Any tips would be appreciated! Kind regards, Douwe Brink

If you're set on an array, you can make it an array of some common parent of what you want to use.. The simplest would of course be an object[][], but the thing that is tripping you up is this fixation on making a walkway an int and a shelf an object.. It seems more sensible to model everything in a warehouse as some kind of derivative of a base class, rather than have walkways be ints of 0/1..

class WarehouseEntity {} 

class Wall:WarehouseEntity{}
class Walkway:WarehouseEntity{}
class Shelf:WarehouseEntity{}


var warehouse = new WarehouseEntity[5,10] ...

Now you can put a wall, walkway or shelf anywhere in your array.. A walkway could have a list of Person that are currently standing in that 10 square meters (or whatever) of Walkway. A Shelf could have a list of products it contains etc. A wall doesn't do much, but it could be handy to record as a wall because maybe you just want to have all kinds of WarehouseEntity have a Bitmap graphic of what they are, and rendering them is just looping over the warehouse array asking each element for its bitmap, rather than saying "if it's a wall, draw a wall, if it's a walkway, draw a walkway.."

class WarehouseEntity {
  Point Coordinates {get; set;}
  abstract Bitmap GetBitmap();
} 

class Wall:WarehouseEntity{

  override Bitmap GetBitmap(){ return _wall_bmp; }
}

class Walkway:WarehouseEntity{

  public List<Person> PeopleStandingHere;
  override Bitmap GetBitmap(){ return _walkway_bmp; }
}

class Shelf:WarehouseEntity{

  public List<Product> ProductsOnShelf;
  override Bitmap GetBitmap(){ return _walkway_bmp; }
}

...
foreach(var we in warehouse)
{
  graphics.DrawImage(we.GetBitMap(), we.Coordinates.X, we.Coordinates.Y);
}

..polymorphism, baby! :)
