INATraversalResultQuery.FeatureClass Property (ArcObjects .NET 10.6 SDK)
ArcObjects Library Reference (NetworkAnalyst)  

INATraversalResultQuery.FeatureClass Property

The feature class by element type.

[Visual Basic .NET]
Public Function get_FeatureClass ( _
    ByVal networkElementType As esriNetworkElementType _
) As IFeatureClass
[C#]
public IFeatureClass get_FeatureClass (
    esriNetworkElementType networkElementType
);
[C++]
HRESULT get_FeatureClass(
  esriNetworkElementType networkElementType,
  IFeatureClass** FeatureClass
);
[C++]

Parameters networkElementType [in]
networkElementType is a parameter of type esriNetworkElementType FeatureClass [out, retval]
FeatureClass is a parameter of type IFeatureClass**

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Network Analyst Extension.

Remarks

Use the FeatureClass property to return a feature class holding all of the NATraversalResultElements of a specific type (esriNETJunction, esriNETEdge, esriNETTurn).

This feature class can be accessed like any other feature class in ArcGIS.

[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(INALayer naLayer, IMap map)
{
  INATraversalResultQuery traversalResultQuery=naLayer.Context.Result;
  INATraversalResultEdit naTraversalResultEdit=traversalResultQuery as INATraversalResultEdit;

  // Infer Geometry
  naTraversalResultEdit.InferGeometry(string.Empty, null, new CancelTrackerClass());

  // Get the Edges and add as a layer
  IFeatureLayer featureLayer=new FeatureLayerClass();
  featureLayer.FeatureClass=traversalResultQuery.get_FeatureClass(esriNetworkElementType.esriNETEdge);
  featureLayer.Name=featureLayer.FeatureClass.AliasName;
  map.AddLayer(featureLayer);

  // Get the Junctions and add as a layer
  featureLayer=new FeatureLayerClass();
  featureLayer.FeatureClass=traversalResultQuery.get_FeatureClass(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
