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); ;
