Geodatabase - 删除要素

 //删除要素类.
 //例如:workspacePath=@"G:\doc\gis\1.400\data\pdb.mdb", featureClassPath="res2_4m".
 private void featureClass_delete(string workspacePath, string featureClassPath) {
     ESRI.ArcGIS.Geodatabase.IWorkspaceFactory wsf = new ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactoryClass();
