1.由RasterLayer 得到RasterDataset

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

2.由RasterDataset 到RasterLayer

  IRasterLayer pRasterLayer = new RasterLayerClass(); 

             pRasterLayer.CreateFromDataset(pRasterDataset); 

             axMapControl1.Map.AddLayer(pRasterLayer as ILayer); ;
