KeyNotFound Exception in Dictionary(of T)
- by C Patton
I'm about ready to bang my head against the wall
I have a class called Map which has a dictionary called tiles.
class Map
{
public Dictionary<Location, Tile> tiles = new Dictionary<Location, Tile>();
public Size mapSize;
public Map(Size size)
{
this.mapSize = size;
}
//etc...
I fill this dictionary temporarily to test some things..
public void FillTemp(Dictionary<int, Item> itemInfo)
{
Random r = new Random();
for(int i =0; i < mapSize.Width; i++)
{
for(int j=0; j<mapSize.Height; j++)
{
Location temp = new Location(i, j, 0);
int rint = r.Next(0, (itemInfo.Count - 1));
Tile t = new Tile(new Item(rint, rint));
tiles[temp] = t;
}
}
}
and in my main program code
Map m = new Map(10, 10);
m.FillTemp(iInfo);
Tile t = m.GetTile(new Location(2, 2, 0)); //The problem line
now, if I add a breakpoint in my code, I can clearly see that my instance (m) of the map class is filled with pairs via the function above, but when I try to access a value with the GetTile function:
public Tile GetTile(Location location)
{
if(this.tiles.ContainsKey(location))
{
return this.tiles[location];
}
else
{
return null;
}
}
it ALWAYS returns null. Again, if I view inside the Map object and find the Location key where x=2,y=2,z=0 , I clearly see the value being a Tile that FillTemp generated..
Why is it doing this? I've had no problems with a Dictionary such as this so far. I have no idea why it's returning null. and again, when debugging, I can CLEARLY see that the Map instance contains the Location key it says it does not...
very frustrating.
Any clues? Need any more info?
Help would be greatly appreciated :)
