Func<bool> run = () =>            {                try                {                    using (IConnection conn = cf.CreateConnection())                    {                        using (IModel channel = conn.CreateModel())                        {                            var consumer = createConsumer(channel);                            while (channel.IsOpen)                            {                                Thread.Sleep(10);                                BasicDeliverEventArgs ea = null;                                try                                {                                    ea = consumer.Queue.DequeueNoWait(null);                                    if (ea == null) continue;                                }                                  catch (Exception ex)                                {                                    TraceLogHelper.WriteError("RabbitMQ", "【里面】", ex.StackTrace);                                    break;                                }                                var body = ea.Body;                                var message = Encoding.UTF8.GetString(body);                                var b = func(message);                                if (b)                                {                                    channel.BasicAck(ea.DeliveryTag, false);                                    Console.WriteLine("接收消息成功:" + message);                                }                                     }                        }                    }                    return true;                }                catch (Exception ex)                {                    TraceLogHelper.WriteError("RabbitMQ", "[外层]", ex.StackTrace);                    return false;                }            };

　　

增加一个 Thread.Sleep(10);即可解决。

 

以后遇到无线循环的时候，需要加Sleep
