Time for action – implementing loading and saving

1. In the Tile Engine project open the TileMap.cs class file.

2. Add the Loading and Saving Maps region to the TileMap class:

   #region Loading and Saving Maps
   public static void SaveMap(FileStream fileStream)
   {
       BinaryFormatter formatter = new BinaryFormatter();
       formatter.Serialize(fileStream, mapCells);
       fileStream.Close();
   }
   
   public static void LoadMap(FileStream fileStream)
   {
       try
       {
           BinaryFormatter formatter = new BinaryFormatter();
           mapCells =(MapSquare[,])formatter.Deserialze(fileStream);
           fileStream.Close();
       }
       catch
       {
           ClearMap();
       }
   }
   
   public static void ClearMap()
   {
       for (int x = 0; x < MapWidth; x++)
           for (int y = 0; y < MapHeight; y++)
               for (int z = 0; z < MapLayers; z++)
               {
                   mapCells[x, y] = new MapSquare(2, 0, 0, "", true);
               }
   }
   #endregion

3. Back in the Level Editor project, open the MapEditor form in Design mode...
