Extract requested fields from query/response

Hi there,

I would like to ask if there is an easy way to access requested fields from an executed query?

My processing looks like that:

1) receive query-string from external source
2) create GraphQLRequest(string)
3) client.SendQueryAsync>(graphqlRequest)

For some reason I need the data which was requested, if the query returns data its quite easy (as I may use the json to derive fields from), but I now need that also for the case that no data is returned.

Thanks in advance,
Stefan
