GeoRegion3D 点击触发事件及获取当前对象

Answer 1

用mapControl_GeometrySelected事件，在事件中用map.findselection()去获取到选择集，然后转换为记录集，再从记录集里面获取出对象；

Selection[] selections = mapControl.findselection(true)
Selection      selection = selections[0];
Recordset rdst = selection.ToRecordset();
Geometry geometry = rdst.GetGeometry();
