具体使用

class Program
    {
        static void Main(string[] args)
        {
            //初始化交换机
            RabbitMQHelper.SetExchange("ServerDirect", "direct");
 
            // 初始化队列
            RabbitMQHelper.SetQueue("LogCenter", "ServerDirect");
            RabbitMQHelper.SetQueue("SMSCenter", "ServerDirect");
            RabbitMQHelper.SetQueue("EmailCenter", "ServerDirect");
 
            //发布消息
 
            for (int i = ; i < ; i++)
            {
                RabbitMQHelper.Publish("ServerDirect", "LogCenter", "log"+i);
            }  
 
            RabbitMQHelper.Publish("ServerDirect", "SMSCenter", "sms111111111");  
 
            Console.ReadKey();
        }
