Get Layers from WebMap (PortalItem)

Question

Is there a way to search the current portal for all WebMaps that contain a certain feaureservice layer?

I can use the myPortal.SearchForContentAsync(query) to get my webmap portal items. But don't see how to get a list of layers for the webmap.   The GetItems() method returns nothing.

Looks like the ArcGIS API can do it, but I need to use the SDK.  Any ideas?

Thanks,

tim

There is a lower level API called EsriHttpClient. You can use it to issue HTTP formatted GET requests (as well as POST, etc.) against the portal. In this way u can use the ArcGIS API as u mention, just parse the returned JSON using Newtonsoft.JSON as needed.

Take a look at all the examples here: https://prodev.arcgis.com/en/pro-app/latest/sdk/api-reference/topic9050.html which is part of the API Reference. They show various usages based off the ArcGIS REST API and will show u the pattern to use.

There are also a couple of samples that use EsriHttpClient as well. Here's one you can look at for additional context: https://github.com/Esri/arcgis-pro-sdk-community-samples/tree/master/Content/PortalInfoListAllFedServers
