两代码的区别

1，

  var cf = new ConnectionFactory { Uri = Uri, RequestedHeartbeat = 30 };

while (innerTaskRunning)
               {
                 using (var conn = cf.CreateConnection())
                   {
                       while (innerTaskRunning)
                       {
                           using (var ch = conn.CreateModel())
                           {
                               try
                               {
                                   ch.ExchangeDeclare(ExchangeName, exchangeType, true);
                                   ch.QueueDeclare(QueueName, true, false, false, Args);
                               }
                               catch (Exception exBind)
                               {
                                   WriteLog(logFunc, "绑定队列出错！q=" + QueueName, exBind);
                                   return false; //异常跳出
                               }

                               var consumer = new QueueingBasicConsumer(ch);
                               var consumerTag = ch.BasicConsume(QueueName, true, consumer);

                               BasicDeliverEventArgs e;
                               using (new MqWatch("BasicConsume", Uri, ExchangeName, QueueName))
                               {
                                   e = (BasicDeliverEventArgs)consumer.Queue.Dequeue();
                               }
                               var msg = Encoding.UTF8.GetString(e.Body); //这儿是消息内容
                               e = null;
                               try
                               {

                                   consumeFunc(msg);
                               }
                               catch (Exception exConsume)
                               {
                                   WriteLog(logFunc, "消费出错，msg=" + msg, exConsume);
                                   //add log
                               }
                           }

                       } //end while
                   }
               }

 

 

  var cf = new ConnectionFactory { Uri = Uri, RequestedHeartbeat = 30 };

while (innerTaskRunning)
               {
                

                   using (var conn = cf.CreateConnection())
                   {
                          using (var ch = conn.CreateModel())
                           {
                               try
                               {
                                   ch.ExchangeDeclare(ExchangeName, exchangeType, true);
                                   ch.QueueDeclare(QueueName, true, false, false, Args);
                               }
                               catch (Exception exBind)
                               {
                                   WriteLog(logFunc, "绑定队列出错！q=" + QueueName, exBind);
                                   return false; //异常跳出
                               }

                               var consumer = new QueueingBasicConsumer(ch);
                               var consumerTag = ch.BasicConsume(QueueName, true, consumer);

                         while (innerTaskRunning)
                       {

                                BasicDeliverEventArgs e;
                               using (new MqWatch("BasicConsume", Uri, ExchangeName, QueueName))
                               {
                                   e = (BasicDeliverEventArgs)consumer.Queue.Dequeue();
                               }
                               var msg = Encoding.UTF8.GetString(e.Body); //这儿是消息内容
                               e = null;
                               try
                               {

                                   consumeFunc(msg);
                               }
                               catch (Exception exConsume)
                               {
                                   WriteLog(logFunc, "消费出错，msg=" + msg, exConsume);
                                   //add log
                               }
                           }

                       } //end while
                   }
               }

 

 

第二段代码内存泄漏的风险。 一直无法释放  BasicDeliverEventArgs  。

但是第二段代码写起来却是错的。

 

应用使用BasicGet ACK的方式取得.
