Engine中如何直接根据点坐标构建IPolyline？

IFeature feature = featureClass.CreateFeature(); 



WKSPoint[] pts = new WKSPoint[2]; 



pts[0].X = -1737894.182; pts[0].Y = 3037754.065; 

pts[1].X = -1139212.740; pts[1].Y = 3095959.205; //点坐标



IPointCollection4 pointCol = new PolylineClass(); 

IGeometryBridge2 geometryBridge2 = new GeometryEnvironmentClass(); 

geometryBridge2.AddWKSPoints(pointCol, ref pts); 

IPolyline polyline = pointCol as IPolyline; 

polyline.SpatialReference = (featureClass as IGeoDataset).SpatialReference; 



ITopologicalOperator topo = polyline as ITopologicalOperator; 

topo.Simplify(); 



feature.Shape = polyline as IGeometry; 

feature.Store();
