NET客户端编程中发生异常“ AMQP操作被中断”（代码= 406） [英] Exception 'The AMQP operation was interrupted' (code=406) occurs in .NET Client programming

问题描述

我有一个2.8.2 RabbitMQ Server和一个2.8.2客户端dll，具有声明队列并获取消息的代码，它可以正常工作（所有参数都是正确的）：

I have a 2.8.2 RabbitMQ Server and a 2.8.2 client dll, have the code to declare a queue and get a message, it works correctly (all parameters are correct):

IModel channel=null;

ConnectionFactory factory = new ConnectionFactory ();
factory.HostName = "192.168.68.4";
_QueueName = "172.16.1.1";

factory.UserName = "guest";
factory.Password = "guest";
factory.VirtualHost = "/";

factory.RequestedHeartbeat = 30;

if (factory.Endpoint == null) {
    Console.WriteLine (" factory.Endpoint==null ");
}


// 接受消息的队列名称是本地的IP地址
_QueueName = "172.16.1.1";
_RMQConnection = factory.CreateConnection ();

Console.WriteLine ("factory.CreateConnection()");

channel = _RMQConnection.CreateModel ();

channel.QueueDeclare(_QueueName, false, false,false,null);

但是当我下载3.0.1 RabbitMQ Server和3.0.1客户端dll时，我使用的是相同的代码，但有例外：

But when I download 3.0.1 RabbitMQ Server and a 3.0.1 client dll, I use the same code and have the exception:

AMQP操作被中断：AMQP关闭原因，由

推荐答案

当您重新声明具有不同参数的现有队列时，通常会收到该错误消息。在管理控制台中检查队列是否已经存在。如果是这样，请尝试将其删除，然后重新运行您的代码。

You typically get that error message when you re-declare an existing queue with different parameters. Check in the management console to see if the queue already exists. If it does, try deleting it and then re-running your code.
