C# + ArcEngine 栅格转矢量

以栅格转点为例：

     public IGeoDataset RasterDataToPointFeatureData(IRasterDataset pRasterDataset,string factory,string name)
        {
            IGeoDataset pRasterGeoDataset = pRasterDataset as IGeoDataset;

            IWorkspaceFactory2 pWorkspaceFactoryShp = new ShapefileWorkspaceFactoryClass();
            IWorkspace pWorkspace = pWorkspaceFactoryShp.OpenFromFile(factory, 0);

            IConversionOp pConversionOp = new RasterConversionOpClass();

            IGeoDataset pGeoDataset = pConversionOp.RasterDataToPointFeatureData(pRasterGeoDataset, pWorkspace, name);

            return pGeoDataset;
        }
