Implementing a 2D Map | 易学教程

问题

I posted a Q. earlier about arrays and the replies lead me to change my game design. I'm building a 2D game map from tiles (Cells). I need to add a pen line to some cells, representing a wall you cannot pass through. This pen line is represented by Cell.TopWall, Cell.BottomWall etc etc of type boolean as shown in my code. This is my whole app so far. It draws the grid without the pen lines for walls. Take note of commented out code where i have tried different things like stating where the walls go with an array of 0's (no wall) and 1's (walls). My question is, can i get a hint on how to implement the walls where i would like? I hope i have shared enough information about my app. Thanks

Cell.cs

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Map
{
    public class Cell : PictureBox
    {
        bool LeftWall; 
        bool TopWall; 
        bool RightWall;
        bool BottomWall;
    }
}
