我设法正确地创建了一个发送者和要发送到RabbitMQ的消息，但是当使用上面给出的方法设置消费者时，它所做的只是消费消息，richtextbox控件没有更新，我也无法在Console中看到消息。我尝试在窗体加载事件和单击按钮事件调用该方法，结果相同，从服务器消耗消息，但在接口上没有返回

public async Task GetMessages()
        {
            try
            {
                var factory = new ConnectionFactory()
                {
                    HostName = "localhost",
                    UserName = "guest",
                    Password = "guest"
                };
                using (var connection = factory.CreateConnection())
                using (var channel = connection.CreateModel())
                {
                    channel.QueueDeclare(queue: "administrator_queue", durable: false, exclusive: false, autoDelete: false, arguments: null);

                    var consumer = new AsyncEventingBasicConsumer(channel);
                    channel.BasicConsume(queue: "administrator_queue", autoAck: true, consumer: consumer);
                    consumer.Received += async (eventSender, eventArgs) =>
                    {
                        var message = Encoding.UTF8.GetString(eventArgs.Body.ToArray());
                        var currentDate = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");

                        await Task.Run(() =>
                        {
                            Invoke((MethodInvoker)delegate
                            {
                                richTextBox.AppendText($"{currentDate}: {message}\n");
                            });
                        });

                        Console.WriteLine($"Received message: {currentDate}: {message}");
                    };
                }
            }
