API C# 3.17: StopAsync do not Stop QuerySubscription

[Victor.Ermakov]

I want to change Query string:

Code: Select all

                        (new Action(async () => { 
                            await QuerySubscription.StopAsync();//Wait for end QuerySubscription
                            QuerySubscription.SetQuery(OAQuery);//!!!!ERROR System.InvalidOperationException: "Setting sql query is only allowed in status 'Stopped'. Current status is 'Stopping'."
                            await QuerySubscription.StartAsync();
                        }))();

i do synchronous stop->change query->start..

on "change query" generates an Error: System.InvalidOperationException: "Setting sql query is only allowed in status 'Stopped'. Current status is 'Stopping'."

Class OaDpQuerySubscription has a not public Property Status. The Status go to state "Stopped" on disconnection of Server. How to I check the Status before calling a StopAsync?
