ArcEngine二次开发之遍历要素类

1.遍历

遍历所有要素类。

下面展示的方法可以直接调用。

        public static List<IFeatureClass> GetAllFeatureClass(IWorkspace workspace)
       {
            IEnumDataset enums = workspace.get_Datasets(esriDatasetType.esriDTAny);
            IDataset dataset = enums.Next();
            List<IFeatureClass> featureclass = new List<IFeatureClass>();
            while (dataset != null)
            {
                esriDatasetType type = dataset.Type;
                if (type == esriDatasetType.esriDTFeatureClass)
                {
                    IFeatureClass fc=dataset as IFeatureClass;
                    featureclass.Add(fc);
                }
                else if (type == esriDatasetType.esriDTFeatureDataset)
                {
                    IFeatureDataset fdataset = dataset as IFeatureDataset;
                    IFeatureClassContainer fcc = fdataset as IFeatureClassContainer;
                    IEnumFeatureClass efc = fcc.Classes;
                    IFeatureClass fclass = efc.Next();
                    while (fclass != null)
                    {
                        featureclass.Add(fclass);
                        fclass = efc.Next();
                    } 
                }
                else
                {
                    continue;
            
                }
                dataset = enums.Next();
            }
            return featureclass;
            
        }
