[ArcGIS Engine]栅格数据处理 RasterDataset RasterLayer Raster RasterBandCollection
1.由RasterLayer 得到RasterDataset

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;
2.由RasterDataset 到RasterLayer

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