Azure service bus - how to add metadata to the message

Question

I am using .net core web app as the publisher and .net core console app as subscriber. I am able to successfully pass messages between these two systems using Managed Identitie

Answer 1

Message object has a property called UserProperties that can be used to set custom metadata for that message.

Something like:

string data = JsonConvert.SerializeObject(payloadEvents);
Message message = new Message(Encoding.UTF8.GetBytes(data));
message.UserProperties.Add("key1", "value1");
message.UserProperties.Add("key2", "value2");

var tokenProvider = TokenProvider.CreateManagedIdentityTokenProvider();

TopicClient sendClient = new TopicClient(_serviceBusNamespace, _topicName, tokenProvider, retryPolicy: null);

await sendClient.SendAsync(message);
