IRaster、IRasterlayer、IRasterdataset之间的转换

 

layer = axMapControl.get_Layer(0);//需要的栅格图层

IRasterLayer rasterlayer = layer as IRasterLayer;

IRaster raster = rasterlayer.Raster;

IRasterBandCollection rasterbandcollection = raster as IRasterBandCollection;

IRasterBand rasterband = rasterbandcollection.Item(0);

IRasterDataset rasterdataset = rasterband as IRasterDataset;
