Graph API filtering users by specific attribute

Question

I'm using the C# Graph API SDK

I have a specific attribute that is formatted like this

extension_{appID}_{attribute}

I want to return only users who have values with this attribute

I've done this but its not supported. I was wondering if there is another way this could be done.

graphServiceClient.Users.Request()
.Filter("extension_{appID}_{attribute} ne null")
.GetAsync();

Answer 1

Try to add ConsistencyLevel header (code for SDK v4)

var options = new List<QueryOption> 
{ 
    new QueryOption("$count", "true") 
}; 

var result = graphServiceClient.Users
                .Request(options)
                .Filter("extension_{appID}_{attribute} ne null")
                .Header("ConsistencyLevel", "eventual")
                .GetAsync();
