为Service Bus worker角色设置OperationTimeOut属性

Question

我正在使用服务总线工作者角色模板创建一个辅助角色.

处理每条消息需要一分多钟的时间.

因此,我看到工作者角色多次收到相同的消息,大约每分钟一条消息.

我想这是因为这个值默认为60秒.

但我不知道如何增加这个值,因为我没有在任何地方看到messageFactorySettings类.

我在哪里设置这个属性？

这是我正在使用的代码

public class WorkerRole : RoleEntryPoint
    {

        // QueueClient is thread-safe. Recommended that you cache 
        // rather than recreating it on every request
        QueueClient Client;
        ManualResetEvent CompletedEvent = new ManualResetEvent(false);

        public override void Run()
        {

            Client.OnMessage((receivedMessage) =>
                {
                    ProcessMessage(recievedMessage);
                });

            CompletedEvent.WaitOne();
        }

        public override bool OnStart()
        {
            ServicePointManager.DefaultConnectionLimit = 12;

            string connectionString = ConfigurationUtility.GetConnectionString("Microsoft.ServiceBus.ConnectionString");
            string queneName = ConfigurationUtility.GetConnectionString("QueueName");

            // Create the queue if it does not exist already
            var namespaceManager = NamespaceManager.CreateFromConnectionString(connectionString);
            if (!namespaceManager.QueueExists(queneName))
            {
                namespaceManager.CreateQueue(queneName);

            }

            Client = QueueClient.CreateFromConnectionString(connectionString, queneName);
            return base.OnStart();
        }

        public override void OnStop()
        {
            // Close the connection to Service Bus Queue
            Client.Close();
            CompletedEvent.Set();
            base.OnStop();
        }
    }

使用ConnectionStringBuilder比自己创建MessagingFactory所需的地址更容易使用:

var builder = new  ServiceBusConnectionStringBuilder(_connectionString)
{
OperationTimeout = TimeSpan.FromMinutes(2) 
};

var messagingFactory = MessagingFactory.CreateFromConnectionString(builder.ToString());
var queueClient = MessagingFactory.CreateQueueClient(_queuePath);
