string json = "{\"hasM\":true,\"paths\":[[[5,4,6],[6,4,5],[8,6,7]]],\"spatialReference\":{\"wkid\":4326}}";
Polyline polyline = PolylineBuilderEx.FromJson(json);
Polyline outputPolyline = GeometryEngine.Instance.ReverseMs(polyline) as Polyline;
// The xy-coordinates in outputPolyline are not changed. 
// The M-values in outputPolyline are: { 7, 5, 6 }
