Question

Sorry for the title i will put here an example of what i want to accomplish:

namespace mdclass
{
  class pClass
  {
    static void Main()
    {
      tiles<int> tl = new tiles<int>();
      tl[0].X = 0;
    }
  }

  class tiles<T> : List<T>
  {
    public int X
    {
      //get/set the X-coordonate
    }

    public int Y
    {
      //get/set the Y-coordonate
    }

  }
}

how can i transfer the [0] from the tl[0] in the public int X and work with it?

Answer 1

Create a class for x and y coordinates:

public sealed class Point {
    public int X { get; set; }
    public int Y { get; set; }
}

Use the Point class to store the coordinates into the list:

public sealed class Program {
    public static void Main() {
        var tiles = new List<Point>();
        tiles.Add(new Point { X = 5, Y = 10 });

        tiles[0].X = 15;
    }
}
