Okay, so I have a dictionary of types int and Tile. I have a class called TileManager that I'm designing to return a NEW instance of a certain tile. Right now this is what I have.

public class TileManager
{
    private Dictionary<int, Tile> _registeredTiles = new Dictionary<int, Tile>();

    public Tile GetNewTile(int id)
    {
        // Here, I need to return a new instance of the tile at the given key. I want
        // something like this: return new _registeredTiles[id].GetType();
    }
    . . .
}

The problem is, I can't just create a new Tile class, because it will be holding different classes other than tiles (it will be holding children of Tile).

    Are you saying you have multiple inheritance of Tile something like SquareTile, CircleTile..etc? or you want to clone the instance stored in _registeredTiles – OKEEngine Sep 22 '13 at 23:17
  • You could use a Factory. See this post: http://stackoverflow.com/questions/3578648/type-casting-and-the-factory-pattern – Caleb Sep 22 '13 at 23:22
  • "holding different classes" implies `Dictionary` (with types restricted to `Tile` and derived ones), but your post shows different declaration `Dictionary`. Which one is correct? – Alexei Levenkov Sep 22 '13 at 23:35
  • By that I meant I have different classes inherited from Tile. – CreeperInATardis Sep 22 '13 at 23:48

The simplest solution would be to use Activator.CreateInstance();

You can pass it a type and an array of constructor arguments if required:

return (Tile)Activator.CreateInstance(_registeredTiles[i].GetType());
