            IFeature newFeature = ipFeatureClass.CreateFeature();
            newFeature.Shape = leftGeometry;
            newFeature.Store();
            IFeature newFeature2 = ipFeatureClass.CreateFeature();
            newFeature2.Shape = rightGeometry;
            newFeature2.Store();
            pWorkspaceEdit.StopEditOperation();
            ipFeature.Delete();
            this.MapControl.ActiveView.Refresh();
        }
请教各位高手，以上为线分割线、线分割面函数，但
实际效果是线分割线可以，线分割面不成功，不知何故。
