[C#]

This C# example shows how you can add a feature class returned by the FeatureClass property on INATraversalResultQuery to a map.


public void AddNATraversalResultToMap(ESRI.ArcGIS.NetworkAnalyst.INALayer naLayer, ESRI.ArcGIS.Carto.IMap map)


{


  ESRI.ArcGIS.NetworkAnalyst.INATraversalResultQuery traversalResultQuery = naLayer.Context.Result as ESRI.ArcGIS.NetworkAnalyst.INATraversalResultQuery;


  ESRI.ArcGIS.NetworkAnalyst.INATraversalResultEdit naTraversalResultEdit = traversalResultQuery as ESRI.ArcGIS.NetworkAnalyst.INATraversalResultEdit;


 


  // Infer Geometry


  naTraversalResultEdit.InferGeometry(string.Empty, null, new ESRI.ArcGIS.Display.CancelTrackerClass());


 


  // Get the Edges and add as a layer


  ESRI.ArcGIS.Carto.IFeatureLayer featureLayer = new ESRI.ArcGIS.Carto.FeatureLayerClass();


  featureLayer.FeatureClass = traversalResultQuery.get_FeatureClass(ESRI.ArcGIS.Geodatabase.esriNetworkElementType.esriNETEdge);


  featureLayer.Name = featureLayer.FeatureClass.AliasName;


  map.AddLayer(featureLayer);


 


  // Get the Junctions and add as a layer


  featureLayer = new ESRI.ArcGIS.Carto.FeatureLayerClass();


  featureLayer.FeatureClass = traversalResultQuery.get_FeatureClass(ESRI.ArcGIS.Geodatabase.esriNetworkElementType.esriNETJunction);


  featureLayer.Name = featureLayer.FeatureClass.AliasName;


  map.AddLayer(featureLayer);


}

[Visual Basic .NET]

This VB.NET example shows how you can add a feature class returned by the FeatureClass property on INATraversalResultQuery to a map.

Public Sub AddNATraversalResultToMap(ByVal naLayer As INALayer, ByVal map As IMap)
    Dim traversalResultQuery As INATraversalResultQuery = naLayer.Context.Result
    Dim naTraversalResultEdit As INATraversalResultEdit = traversalResultQuery

    ' Infer Geometry
    naTraversalResultEdit.InferGeometry(String.Empty, Nothing, New CancelTracker())

    ' Get the Edges and add as a layer
    Dim featureLayer As IFeatureLayer = New FeatureLayer()
    featureLayer.FeatureClass = traversalResultQuery.FeatureClass(esriNetworkElementType.esriNETEdge)
    featureLayer.Name = featureLayer.FeatureClass.AliasName
    map.AddLayer(featureLayer)

    ' Get the Junctions and add as a layer
    featureLayer = New FeatureLayer()
    featureLayer.FeatureClass = traversalResultQuery.FeatureClass(esriNetworkElementType.esriNETJunction)
    featureLayer.Name = featureLayer.FeatureClass.AliasName
    map.AddLayer(featureLayer)
End Sub
