C# - Fast simple object serialization
===

I am looking for fastest serialization method tiles in 2D world. Lets say the world is big and because computer can't handle that much blocks loaded at the same time, so I splitted the world to chunks. `BinaryFormatter` seems to be slow. Is there any faster method, how to serialize the chunk object?

WChunk object structure

    public class WChunk
    {
        public int ChunkX;
        public int ChunkY;
        public SortedDictionary<WPoint, WTile> Tiles;
    }

WTile object structure

    public class WTile
    {
        WPoint Location;
        int Data;
    }

Thanks for answers!
