Geodatabase - 删除要素

 1 //删除要素类.

 2 //例如:workspacePath=@"G:\doc\gis\1.400\data\pdb.mdb", featureClassPath="res2_4m".

 3 private void featureClass_delete(string workspacePath, string featureClassPath) {

 4     ESRI.ArcGIS.Geodatabase.IWorkspaceFactory wsf = new ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactoryClass();

 5     ESRI.ArcGIS.Geodatabase.IWorkspace ws = wsf.OpenFromFile(workspacePath, 0);

 6     ESRI.ArcGIS.Geodatabase.IFeatureWorkspace fws = (ESRI.ArcGIS.Geodatabase.IFeatureWorkspace)ws;

 7     ESRI.ArcGIS.Geodatabase.IFeatureClass fc = fws.OpenFeatureClass(featureClassPath);

 8     //注意的是这里需要为IDataset(IFeatureClass没有删除的功能).

 9     ESRI.ArcGIS.Geodatabase.IDataset ds = (ESRI.ArcGIS.Geodatabase.IDataset)fc;

10     ds.Delete();
