C#使用rabbitmq在接收消息事件处理中，同时发布消息报错：

Already closed: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=505, text='UNEXPECTED_FRAME - expected content header for class 60, got non content header frame instead', classId=60, methodId=40

解决办法是将接收事件代码里面末尾加个线程休眠“System.Threading.Thread.Sleep(1);”，不然发布方法调用报错，参考代码

              }
              System.Threading.Thread.Sleep(1);//此行代码必须，不然写入队列消息会报错
