Display directions for a route between two points.
Use case
Find routes with driving directions between any number of locations. You might use the ArcGIS platform to create a custom network for routing on a private roads.
How to use the sample
For simplicity, the sample comes loaded with a start and end stop. You can tap on the Find Route button to display a route between these stops. Once the route is generated, turn-by-turn directions are shown in a list.
How it works
- Create a
RouteTaskusing a URL to an online route service. - Generate default
RouteParametersusingrouteTask.CreateDefaultParametersAsync(). - Set
returnStopsandreturnDirectionson the parameters to true. - Add
Stops to the parametersstopscollection for each destination. - Solve the route using
routeTask.SolveAsync(routeParameters)to get aRouteResult. - Iterate through the result's
Routes. To display the route, create a graphic using the geometry fromroute.RouteGeometry. To display directions, userouteDirectionManeuvers, and for eachDirectionManeuver, displayDirectionManeuver.DirectionText.
