清除蔚蓝服务总线队列一气呵成 [英] Clearing azure service bus queue in one go

问题描述

我们在我们的项目中使用服务总线队列。我们需要的功能，从队列中删除所有邮件管理员选择以清除队列。我在网上搜索，但没有找到它做到这一点的 QueueClient 类中的任何功能。

我一定要弹出所有的消息一个接一个，然后将它们标记完全清除队列或是否有更好的办法吗？

  QueueClient queueClient = _messagingFactory.CreateQueueClient（
                              queueName，ReceiveMode.PeekLock）;

BrokeredMessage brokeredMessage = queueClient.Receive（）;

而（brokeredMessage！= NULL）
{
    brokeredMessage.Complete（）;
    brokeredMessage = queueClient.Receive（）;
}
 

解决方案

有关Azure的ServiceBus-队列存在的 ReceiveBatch -method ，让您能够接收一批的 N 的-messages的时间。结合 ReceiveMode.ReceiveAndDelete 您可以更有效地清除队列。

买者的数量的的消息正的可能会返回，但它不能保证。也有对 256K 的消息批次大小的限制

We are using a service bus queue in our project. We are in need of a functionality to remove all the messages from the queue when the administrator chooses to clear the queue. I searched on the net but could not find any function which does this inside the QueueClient class.

Do I have to pop all the messages one by one and then marking them complete to clear the queue or is there a better way?

QueueClient queueClient = _messagingFactory.CreateQueueClient(
                              queueName, ReceiveMode.PeekLock);

BrokeredMessage brokeredMessage = queueClient.Receive();

while (brokeredMessage != null )
{
    brokeredMessage.Complete();
    brokeredMessage = queueClient.Receive();
}

解决方案

For Azure-ServiceBus-Queues there is a ReceiveBatch-method which allows you to receive a batch of n-messages at the time. Combined with ReceiveMode.ReceiveAndDelete you can clear the queue more efficiently.

Caveat The number n of messages might be returned but it's not guaranteed. Also there is a limit for the message-batch size of 256K.
