                        pFillSymbol.Outline = pLineSymbol;

                        ISimpleRenderer pSimpleRender = new SimpleRendererClass();

                        pSimpleRender.Symbol = pFillSymbol as ISymbol;

                        IGeoFeatureLayer pGeoFeatureLayer = pFeatureLayer as IGeoFeatureLayer;

                        pGeoFeatureLayer.Renderer = pSimpleRender as IFeatureRenderer;
