How to parse the response from insert?

[RobvanB]

I'm using the MS sample code to create a journal using OData.
I can create the header fine.
However, when the header is created, the journal number is returned in the response.
How do I get the journal number from the response?

The record is created using
resp = context.SaveChanges();

resp is of type DataServiceResponse, and contains the data in Json format (if I understand this correctly) - but I'm having trouble pulling gout the one field with the new journal ID.
How do I get the new journal ID from the response?

        DataServiceResponse response = context.SaveChanges(SaveChangesOptions.PostOnlySetProperties);
        
        foreach (ChangeOperationResponse change in response)
        {
            EntityDescriptor descriptor = change.Descriptor as EntityDescriptor;

            if (descriptor != null)
            {

                var ret_entity = descriptor.Entity as NameOfYourEntity;
                
                ..do whatever you need to do with ret_entity should have all of the props available and populated for you from your newly inserted record

            }
        }
