how to get list of all devices from intune via Graph.Intune namespace in .Net?

Question

I am trying to get a list of all devices in InTune, using c# /.Net.
All examples show how to do this on a per user basis only, but this seems inefficient, to have to iterate through all users.

There appears to be a Powershell command that can do this. is this functionality available in the Microsoft.Graph .net namespace?
I have been unable to find it.

Answer 1

@na , Based on my test in my lab, I find we can using the following method to get all the managed devices in graph.

1. Open Intune portal, press F12 to open Devtools. Add Network console to capture the network record.
2. Click Devices->All devices in Intune portal.
3. Then stop record and go to check the request information. I find the request is as below:
   Request method: Get
   Request URl: https://graph.microsoft.com/beta/deviceManagement/managedDevices?$filter=(Notes%20eq%20%27bc3e5c73-e224-4e63-9b2b-0c36784b7e80%27)&$top=25&$skipToken=Skip=%270%27&$select=deviceName,managementAgent,ownerType,complianceState,deviceType,userId,userPrincipalName,osVersion,lastSyncDateTime,userPrincipalName,id,deviceRegistrationState,managementState,exchangeAccessState,exchangeAccessStateReason,deviceActionResults,deviceEnrollmentType

4. You can find the one in your environment and try to request in graph explorer to get the managed device information:

Hope it can help.

How do i execute that ODATA url in .net core though?
Ive used the graph api in .net to query users, but it does not seem to have the flexibility thats available via odata calls in Graph Explorer.

Thanks @Crystal-MSFT

There is a graph API which is very useful, but limited and does not appear to provide access to devices, only to query devices on a per person/UPN basis.
I have managed to access this using a more generic http request, obtain a token from azure identity and create the URL within the .NET app.

Requires more coding but it works.

Thank you for your help and direction on this.
