Question

我试图在服务总线主题订阅中创建过滤规则。

 foreach(var reciver in recivers)
        {
            try
            {
                var client = SubscriptionClient.CreateFromConnectionString(ServiceBusConnectionString, reciver.TopicName, reciver.SubscriptionName);

                string ruleName = "customRule2";
                client.RemoveRule(ruleName);

                var filter = reciver.Reciver.GetFilter();
                var ruleDescription = new RuleDescription(ruleName, filter);

                client.AddRule(ruleDescription);
                client.RemoveRule("$Default");

                client.OnMessage((msg) => {
                    reciver.Reciver.Recive(msg);
                });                    
            }
            catch(Exception ex)
            {

            }
        }

异常来自

client.AddRule(ruleDescription);

我尝试删除以下行

client.RemoveRule(ruleName);

它正常工作。但是第二次运行应用程序时，它会出现异常情况＆＃34;消息传递实体已经存在＆＃34;

但是我需要删除现有规则并在启动订阅时添加相同的规则。

以下是完整的异常消息

Answer 1

WindowsAzure.ServiceBus.dll版本存在问题。我将WindowsAzure.ServiceBus.dll的版本从4.1.3降级到4.1.2，这是完美的。

编辑：这个问题又来了

无法添加Azure Service Bus主题订阅过滤规则
