Question

arcengine 怎么加载DEM数据呀 求C#代码

Answer 1

　方法一、通过遍历CAD数据集，依次加载中点线面注记等图层，所加载的数据均为一个独立的图层。
　　IWorkspaceFactory pWorkspaceFactory;
　　IFeatureWorkspace pFeatureWorkspace;
　　IFeatureLayer pFeatureLayer;
　　IFeatureDataset pFeatureDataset;
　　//打开CAD数据集
　　pWorkspaceFactory = new CadWorkspaceFactoryClass();
　　pFeatureWorkspace = (IFeatureWorkspace)pWorkspaceFactory.OpenFromFile(directoryPath, 0);
　　//打开一个要素集
　　pFeatureDataset = pFeatureWorkspace.OpenFeatureDataset(fileName);
　　//IFeaturClassContainer可以管理IFeatureDataset中的每个要素类
　　IFeatureClassContainer pFeatureClassContainer = (IFeatureClassContainer)pFeatureDataset;
　　//对CAD文件中的要素进行遍历处理
