Engine中执行缩放到全图时，可否控制其范围？

​ IMap map = axMapControl1.ActiveView.FocusMap;

            IFeatureLayer featureLayer = map.get_Layer(0) as IFeatureLayer;

            IFeature feature = featureLayer.FeatureClass.GetFeature(270);

            map.AreaOfInterest = feature.ShapeCopy.Envelope;

            axMapControl1.Extent = axMapControl1.FullExtent;

            axMapControl1.Refresh();
