1  IRasterLayer myrasterlayer = MapControl.Map.Layer[index] as IRasterLayer;
2                 IRaster myRaster = myrasterlayer.Raster;
3                 IRasterBandCollection myRasterBandCollection = myRaster as IRasterBandCollection;
4                 IRasterBand myRasterBand = myRasterBandCollection.Item(0);
5                 IRasterDataset myRasterDataset = myRasterBand as IRasterDataset;

 .由RasterLayer 得到RasterDataset

RasterLayer->RasterDataset
IRasterLayer myrasterlayer = MapControl.Map.Layer[index] as IRasterLayer;
IRaster myRaster = myrasterlayer.Raster;
IRasterBandCollection myRasterBandCollection = myRaster as IRasterBandCollection;
IRasterBand myRasterBand = myRasterBandCollection.Item(0);
IRasterDataset myRasterDataset = myRasterBand as IRasterDataset;

2.由RasterDataset 到RasterLayer

1  IRasterLayer pRasterLayer = new RasterLayerClass(); 
2  
3             pRasterLayer.CreateFromDataset(pRasterDataset); 
4  
5             axMapControl1.Map.AddLayer(pRasterLayer as ILayer); ;

1  IRasterLayer pRasterLayer = new RasterLayerClass(); 
2  
3             pRasterLayer.CreateFromDataset(pRasterDataset); 
4  
5             axMapControl1.Map.AddLayer(pRasterLayer as ILayer); ;
