我使用以下代码在不删除的情况下接收消息。现在我需要添加一些过滤并删除一些消息。我的问题是如何删除特定消息而其他消息应保留在队列中？
Uri connecturi = new Uri("activemq:tcp://model.net:61616");
IConnectionFactory factory = new NMSConnectionFactory(connecturi);
List<ModelBuilderBase> result = new List<ModelBuilderBase>();
using (IConnection connection = factory.CreateConnection())
using (ISession session = connection.CreateSession())
{
IDestination destination = SessionUtil.GetDestination(session, "queue://cidModelbuilderQ");
using (IMessageConsumer consumer = session.CreateConsumer(destination))
{
connection.Start();
var q = session.GetQueue("cidModelbuilderQ");
var b = session.CreateBrowser(q);
var msgs = b.GetEnumerator();
while (msgs.MoveNext())
{
ITextMessage message = msgs.Current as ITextMessage;
if (message.Properties[MANDATOR] == null || message.Properties[REFCODE] == null)
continue;
var mandator = message.Properties[MANDATOR].ToString();
var refCode = message.Properties[REFCODE].ToString();
result.Add(ModelBuilderFactory.Instance.GetInstance(refCode, mandator));
}
}
}
