Given any arcgis server url, i want to fetch all its services in the list box. When i click on any layer from the list box, that layer should be displayed on my map
can anyone pls tell me how to dynamically fetch all services of any arcgis server.
This sample http://blogs.esri.com/esri/apl/2012/03/06/dynamic-image-service-directory/ builds a directory of Image Services which would be the same just don't filter out based on it being an Image Service. Basically you query the service catalog and get the json representation and parse that out into the Service names and associated urls. I myself wrote a rest service that connects from the server side and using ArcObjects gets the inventory and my Silverlight applications calls that service
the link mentioned is not opening. I tried following code from this link http://forums.esri.com/Thread.asp?c=158&f=2276&t=279387 ESRI.ArcGIS.GISClient.IAGSServerConnectionFactory2 connectionFactory; connectionFactory = (ESRI.ArcGIS.GISClient.IAGSServerConnectionFactory2)new ESRI.ArcGIS.GISClient.AGSServerConnectionFactory(); //create a property set to hold connection properties IPropertySet connectionProps; connectionProps = new PropertySet(); //specify the URL for the server connectionProps.SetProperty("URL", "http://services.arcgisonline.com/arcgis/services"); //define username and password for the connection //connectionProps.SetProperty("USER", "<USER>"); //connectionProps.SetProperty("PASSWORD", "<PASS>"); //open the server connection, pass in the property set, get a connection object back ESRI.ArcGIS.GISClient.IAGSServerConnection gisServer; gisServer = connectionFactory.Open(connectionProps, this.Handle.ToInt32());
//get an enum of all server object names from the server (GIS services, i.e.) ESRI.ArcGIS.GISClient.IAGSEnumServerObjectName soNames = gisServer.ServerObjectNames; ESRI.ArcGIS.GISClient.IAGSServerObjectName3 soName; //loop thru all services, find a map service called "I3_Imagery_Prime_World_2D" (high res imagery for the world) soName = (ESRI.ArcGIS.GISClient.IAGSServerObjectName3)soNames.Next(); do { if ((soName.Type == "MapServer") && (soName.Name == "I3_Imagery_Prime_World_2D")) { break; //found it } //keep searching the services ... soName = (ESRI.ArcGIS.GISClient.IAGSServerObjectName3)soNames.Next(); } while (soName != null); //if the desired service was found ... if (soName != null) { //create a layer factory to make a new MapServerLayer from the server object name ILayerFactory msLayerFactory; msLayerFactory = new MapServerLayerFactory(); //create an enum of layers using the name object (will contain only a single layer) IEnumLayer enumLyrs = msLayerFactory.Create(soName); //get the layer from the enum, store it in a MapServerLayer variable IMapServerLayer mapServerLayer; mapServerLayer = (IMapServerLayer)enumLyrs.Next(); //make sure the layer is not empty (Nothing), then add it to the map if (mapServerLayer != null) { IMap.AddLayer((ILayer)mapServerLayer); } }
But here many errors appear as i dont have library reference ESRI.ArcGIS.GISClient.
Can you resend me the link in ur earlier reply. Or check if above code is correct what i am looking for, if yes pls tell me how to i get reference for ESRI.ArcGIS.GISClient
I am not sure about how dbroux application works but I would imagine it has to be similar to what the link I posted for the Imagery application. The imagery application does exactly what you want except it filters to only display Image Services in the tree (basically one conditional statement that would need to be removed).
Get the catalog data from the server rest endpoint. If you put you services url (http://SERVER/arcgis/rest/services?f=json) you can see the json string try (http://SERVER/arcgis/rest/services?f=pjson) for something easier to read. The json can be converted to objects and the catalog built from there. Which is done in the application link I posted.
You can't use ArcObjects at the client side of a silverlight application. You can do it at the server side by creating a SOE (Server Object Extension) but I don't recommend that approach in your case.
Both referenced samples (Joe's one and mine) are using REST to know the folders and the services.
Basically you have to deserialize server answers such as :
Thanks very much for giving response. It really helped me.
Now I am getting error in MapService.cs file There was an error deserializing the object of type ESRI.ArcGIS.ServerExplorer.MapServiceInfo. Data at the root level is invalid. Line 1, position 1.
at the code this.m_mapServiceInfo = dataContractJsonSerializer.ReadObject(memoryStream) as MapServiceInfo;
can you please tell me why this is throwing such error at runtime
