Engine中如何获取缓存服务中各个级别的Scale数值

ITiledMapServer tiledMapServer = mapserver as ITiledMapServer;

            ITileCacheInfo tileCacheInfo = tiledMapServer.GetTileCacheInfo(World Cities Population);

            ILODInfos LODInfos = tileCacheInfo.LODInfos;

            for (int i = 0; i < LODInfos.Count; i++)

            {

                ILODInfo LODInfo = LODInfos.get_Element(i);

                double scale = LODInfo.Scale;

            }
