Adding Line Barriers as NaLocations

[Haider_Ali]

I cant figure out how can i specify line barrier in setPolylineBarriersByRef  of NAServerRouteParams class, 

i know it takes INAServerLocations  but i cant figure out how to provide line in propertySet 

IPropertySet line = new PropertySet();

line.setProperty("paths", polyline);   // cant figure out this

IPropertySetArray pPropSets = new PropertySetArray();

pPropSets.add(line );

//Setting the Server Property Sets for the Network Analysis
INAServerPropertySets propSets = new NAServerPropertySets();

propSets .setPropertySetsByRef(pPropSets);

INAServerLocations2 serverLoc = (INAServerLocations2) propSets ;
return serverLoc;

Hi Haider,

The GISClient API you are referring to is deprecated since version 10.0. If you still have to use it, the following snippet may help:

protected INAServerPropertySets GetPolylineBarriers(int numberOfLocations2Load, double[] candidates)
{
  /* Assumes that candidates is an array of doubles
  * which contains 3 vertices (6 double numbers) per polyline-
  *
  * 3 * (x, y)
  */

  INAServerPropertySets res = new NAServerPropertySetsClass();
  res.PropertySets = new PropertySetArrayClass();

  for (int i = 0; i < numberOfLocations2Load; i++)
  {
    res.PropertySets.Add(new PropertySetClass());

    res.PropertySets.get_Element(i).SetProperty("Name", "Polyline " + (i + 1));

    IPolyline pl = new PolylineClass();
    IPointCollection pcol = pl as IPointCollection;

    object missing = Type.Missing;
    for (int j = 0; j < 3; j++)
    {
      IPoint pnt = new PointClass();
      int xIndex = i * 6 + j * 2;
      pnt.X = candidates[xIndex];
      pnt.Y = candidates[xIndex + 1];

      pcol.AddPoint(pnt, ref missing, ref missing);
    }

    res.PropertySets.get_Element(i).SetProperty("Shape", pl);
  }

  return res;

}

On the other hand, if you are using a newer version of ArcGIS Server I strongly recommend using REST API instead:

Thanks that worked, i.e. line.setProperty("Shape", polyline);   

Actually our requirement is to get multiple alternative route  , so our solution was to use SOE to avoid multiple call to server i.e. in the SOE find the route and provide that route as barrier for next  solve route.
