创建栅格图层的属性表

        /// 根据栅格图层获取栅格数据集
        /// </summary>
        /// <param name="pRasterLayer"></param>
        /// <returns></returns>
        static public IRasterDataset GetRasterDatasetFromRasterLayer(IRasterLayer pRasterLayer)
        {
            //  获取栅格路径
            string pFilePath = pRasterLayer.FilePath;

            //  获取栅格工厂
            IWorkspaceFactory pFactory = new RasterWorkspaceFactoryClass();

            //  获取路径
            string pDir = System.IO.Path.GetDirectoryName(pFilePath);

            //  工作空间
            IWorkspace pSpace = pFactory.OpenFromFile(pDir, 0);

            //  QI 至 IRasterWorkspace
            IRasterWorkspace pRasterSpace = pSpace as IRasterWorkspace;

            //  获取文件名
            string name = System.IO.Path.GetFileName(pFilePath);
            IRasterDataset pDataset = pRasterSpace.OpenRasterDataset(name);

            return pDataset;

        }


        /// <summary>
        /// 创建栅格属性表
        /// </summary>
        /// <param name="pRasterLayer"></param>
        static public void BuildRasterAttributeTable(IRasterLayer pRasterLayer)
        {
            //  获取栅格数据集
            IRasterDataset pDataSet = GetRasterDatasetFromRasterLayer(pRasterLayer);

            //  QI IRasterDatasetEdit2 创建栅格属性表
            IRasterDatasetEdit2 pDataSetEdit = pDataSet as IRasterDatasetEdit2;
            pDataSetEdit.BuildAttributeTable();

        }

2、在Data Management Tools（数据管理工具）->Raster（栅格）->Raster Properties（栅格属性）中选择Build Raster Attribute Table（创建栅格属性表）选中栅格数据，即可创建栅格属性表。

static void BuildRasterAttributeTable(IRasterDataset rasterDataset, ITable table)
{
    //Cast to IRasterDatasetEdit2 to build a raster attribute table.
    IRasterDatasetEdit2 rasterDatasetEdit = (IRasterDatasetEdit2)rasterDataset;

    //Build a default raster attribute table with VALUE and COUNT fields.
    if (table == null)
    {
        rasterDatasetEdit.BuildAttributeTable();
    }
    else
    {
        //Assign the given table as the raster attribute table.
        rasterDatasetEdit.AlterAttributeTable(table);
    }
}
