Issue on ArcGIS SOAP NAServer Namespace

Question

I am trying to create a simple ArcGIS Server SOAP consumer by C# like below snippet but I am getting error on NAService_NAServeras illustrated in attached image. Can you please let me know which namespace I have to use?

I am already using this namespaces

using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Server;
using ESRI.ArcGIS.Geometry;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Carto;

but they are not doing the job!

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.Server;
using ESRI.ArcGIS.Geometry;
using ESRI.ArcGIS.Geodatabase;
using ESRI.ArcGIS.Carto;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            private void SolveRoute()
        {
            // Connect to server
            NAService_NAServer naService = new NAService_NAServer();
            naService.Url = "http://localhost/ArcGIS/services/NetworkAnalysisService/MapServer/NAServer");
            //Get Route layers
            string[] routeLayers = naService.GetNALayerNames(esriNAServerLayerType.esriNAServerRouteLayer);

            // Get the default settings for the first route layer
            NAServerRouteParams naServerRouteParams = (NAServerRouteParams)naService.GetSolverParameters(routeLayers[0]);

            // Create 2 stops as property sets
            List<PropertySet> propertySets = new List<PropertySet>(2);
            propertySets.Add(CreatePropertySet("My starting point", -117.195905, 34.057783));
            propertySets.Add(CreatePropertySet("My ending point", -117.180943, 34.056286));

            // Set the property sets on a NAServerPropertySets object and set on the routeParams object
            NAServerPropertySets naServerPropertySets = new NAServerPropertySets();
            naServerPropertySets.PropertySets = propertySets.ToArray();
            naServerRouteParams.Stops = naServerPropertySets;

            // specify to return compact directions
            naServerRouteParams.ReturnCompactDirections = true;

            // Solve
            NAServerRouteResults naServerRouteResults = (NAServerRouteResults)naServer.Solve(naServerRouteParams);

            // Output directions
            NACompactStreetDirections streetDirections = naServerRouteResults.CompactDirections[0];
            StringBuilder sb = new StringBuilder();
            sb.AppendFormat("DriveTime = {0}", streetDirections.Summary.TotalDriveTime);
            sb.AppendLine();
            foreach (NACompactStreetDirection streetDirection in streetDirections.Directions)
            {
                sb.AppendLine(streetDirection.Text);
            }
            Console.WriteLine(sb.ToString());
        }

    }
    }
}

Answer 1

The namespace depends on what you defined the namespace when added the service reference.
For example:

• I created a new .NET App named "RouteUsingSOAP"
• Right-click on the project and click on "Add > Service Reference"
• Specify the Address to the SOAP endpoint. In my case: http://mymachine:6080/arcgis/services/Routing/NetworkAnalysis/MapServer/NAServer?wsdl
• Specify the Namespace by putting "NAServer"
• Click OK to create the service.

And then the following code works for me:

private void button1_Click(object sender, EventArgs e)
{
  RouteUsingSOAP.NAServer.NAServerPortClient naService = new RouteUsingSOAP.NAServer.NAServerPortClient();
  string[] routeLayers = naService.GetNALayerNames(NAServer.esriNAServerLayerType.esriNAServerRouteLayer);
  foreach (string layerName in routeLayers) {
    listBox1.Items.Add(layerName);
  }
}

Looks like the NASever class was depreciated at 10.1.

At version 10.1, ArcGIS for Server no longer supports performing network analysis via local connections using the GISServer and GISClient APIs. Use the SOAP or REST API instead.
