INAContext.NetworkDataset Property

The associated network dataset.

[Visual Basic .NET]
Public ReadOnly Property NetworkDataset As INetworkDataset

[C#]
public INetworkDataset NetworkDataset {get;}

[C++]
HRESULT get_NetworkDataset(
  INetworkDataset** NetworkDataset
);

[C++]

Parameters
NetworkDataset [out, retval]

  NetworkDataset is a parameter of type INetworkDataset

Product Availability

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

Remarks

NetworkDataset returns the NetworkDataset that the NAContext is referencing.

The NetworkDataset is only available after the NAContext has been bound to a NetworkDataset using INAContextEdit::Bind.

[C#]

This illustrates how you can get the NetworkDataset from the NAContext after it has been bound.

public void CreateContextAndGetNetworkDatasetBackOut(INetworkDataset networkDataset)
{
  INASolver naSolver=new NARouteSolver() as INASolver;
  IDENetworkDataset deNetworkDataset=((IDatasetComponent)networkDataset).DataElement as IDENetworkDataset;
  INAContext context=naSolver.CreateContext(deNetworkDataset, naSolver.DisplayName) as INAContext;
  INAContextEdit contextEdit=(INAContextEdit)context;
  contextEdit.Bind(networkDataset, new GPMessagesClass());
  INetworkDataset networkDatasetFromContext=context.NetworkDataset;
}
