我是否可以查看Azure ServiceBus主题订阅中当前启用的过滤器？

Question

I'd like to let people change their subscription filters via an interface in my app. To do this, I need to show them which filters are currently applied to their subscription.

I cannot find anywhere in the documentation where it allows you to list the current filters.

You have the ability to AddRule and RemoveRule , but no way to list them. RemoveRule will even throw an exception if that rule already exists.

How can I determine which rules are currently being applied to my Topic Subscription?

Answer 1

Yes, you can get list of rules for a specific topic and subscription through NamespaceManager.GetRules(string topicPath, string subscriptionName) :

        var rules = namespaceManager.GetRules("MyTopic", "MySubscriber");
        foreach (var ruleDescription in rules)
        {
            Console.Write(ruleDescription.Name);
            var filter = ruleDescription.Filter;
        }
