[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
