Engine中如何修改拓扑规则检查出来的错误要素？

IFeatureClass pFeatureClass = featureWorkspace.OpenFeatureClass(fc); 

IWorkspaceEdit wkspEdit = featureWorkspace as IWorkspaceEdit; 

wkspEdit.StartEditing(false); 

wkspEdit.StartEditOperation(); 



//将错误要素添加进RuleException

topologyRuleContainer.PromoteToRuleException(topologyErrorFeature); 



IFeature pFeature = pFeatureClass.GetFeature(topologyErrorFeature.OriginOID);

            IGeometry feaGeo = pFeature.Shape;

            ITopologicalOperator5 topo = feaGeo as ITopologicalOperator5;

            topo.IsKnownSimple_2 = false;

            bool isknowsimple = topo.IsKnownSimple;

            topo.Simplify();

            pFeature.Shape = topo as IGeometry;

            pFeature.Store();

            wkspEdit.StopEditOperation();

            wkspEdit.StopEditing(true);



            topologyRuleContainer.DemoteFromRuleException(topologyErrorFeature);
