Classes that implement INAServer

Classes Description
NAServer Deprecated as of 10.0. A MapServer object extension for performing network analysis within a stateless environment.
NAServerIP Deprecated as of 10.0. NAServer Proxy for IP Messages.
NAServerLP Deprecated as of 10.0. NAServer Proxy for LAN messages.


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.

INAServer has been superseded by INAServer2.


This example illustrates connecting to an NAServer web service via a web reference and getting the names of the route layers.

// Assumes you've created a web reference to web service named "SanFrancisco"
SanFrancisco_NAServer pNAServer = new SanFrancisco_NAServer();
pNAServer.Url = "http://localhost:6080/arcgis/services/SanFrancisco/MapServer/NAServer";

// Use NAServer to get analysis layer names
string[] routeLayerNames = pNAServer.GetNALayerNames(esriNAServerLayerType.esriNAServerRouteLayer);
