URGENT-Iterate through Solace Message Queue

Please find a modified version of the QueueConsumer sample, below, which will read all messages from a queue until the user presses a key to close the application:

    static void Run(string host, string vpnname, string username, string password)
    {
        try
        {
            // Initialize Solace Systems Messaging API with logging to console at Warning level
            var props = new ContextFactoryProperties() { SolClientLogLevel = SolLogLevel.Warning };
            props.LogToConsoleError();
            ContextFactory.Instance.Init(props);

            // Define context and session properties
            var contextProperties = new ContextProperties();
            var sessionProperties = new SessionProperties()

                VPNName = vpnname,
                UserName = username,
                Password = password,
                ConnectRetries = DefaultConnectRetries,
            };
            var queueName = "Q/tutorial";
            var flowProperties = new FlowProperties()
            {
                AckMode = MessageAckMode.ClientAck
            };

            // Create context and session instances
            using (var context = ContextFactory.Instance.CreateContext(contextProperties, null))
            using (var session = context.CreateSession(sessionProperties, null, null))
            {
                // Connect to the Solace messaging router
                Console.WriteLine($"Connecting as {username}@{vpnname} on {host}...");
                var connectResult = session.Connect();

                if (connectResult == ReturnCode.SOLCLIENT_OK)
                {
                    Console.WriteLine("Session successfully connected.");

                    using (var queue = ContextFactory.Instance.CreateQueue(queueName))
                    using (var flow = session.CreateFlow(flowProperties, queue, null, HandleMessageEvent, HandleFlowEvent))
                    {

                        Console.WriteLine($"Waiting for a message in the queue '{queueName}'...");
                        Console.WriteLine($"Press any key to exit. ----------------------");
                        Console.WriteLine();
                        Console.ReadKey(true);
                    }
                }
                else

                }
            }
                    
        }
        finally
        {
            // Dispose Solace Systems Messaging API
            ContextFactory.Instance.Cleanup();
        }
        Console.WriteLine("Finished.");
    }
    static void HandleMessageEvent(object source, MessageEventArgs args)

        // Received a message
        Console.WriteLine("Received message.");
        using (IMessage message = args.Message)
