AO中如何获取Map Server的切片方案？

【解决办法】：
1，获取到IMapServer
2，转为ITiledMapServer，其GetCacheDescriptionInfo方法获取到ICacheDescriptionInfo
3，通过ICacheDescriptionInfo.TileCacheInfo属性获取ITileCacheInfo
4，通过ITileCacheInfo.LODInfos获取LODInfos，进而遍历获取到ILODInfo，即可获取LevelID以及Scale

if(mapserver is ITiledMapServer) 

{ 

ITiledMapServer2 tiled = mapserver as ITiledMapServer2; 

ICacheDescriptionInfo cacheDes = tiled.GetCacheDescriptionInfo(mapserver.DefaultMapName); 

ITileCacheInfo cacheInfo = cacheDes.TileCacheInfo; 

ILODInfos lodInfos = cacheInfo.LODInfos; 

for(int i=0;i<lodInfos.Count;i++) 

{ 

ILODInfo info = lodInfos.get_Element(i); 

} 

}
