Send a message with a new library (Microsoft.Azure.ServiceBus) that is read by an old library (Microsoft.ServiceBus.Messaging) with BodyType - String


I have a client written for some time ago that uses the old library and does call GetBody<string>() to read the body when receiving messages.

Now I have the new client Microsoft.Azure.ServiceBus (sends messages) that as far as I understand always uses Stream.

So the old client just crashes as it expects string body type. I have found a lot of information on the opposite scenario (new reader, old writer), but cannot figure out how to make the new client send the data in required format.

Solution

  • The scenario is described here. You will need to serialize the message following this approach:

     var serializer = DataContractBinarySerializer<string>.Instance; 
     using (MemoryStream stream = new MemoryStream()) 
     {
         serializer.WriteObject(stream, some_string);
         var msg = new Message(stream.ToArray());
         var client = new Microsoft.Azure.ServiceBus.QueueClient(ConnectionString, Queue);
         await client.SendAsync(msg);
         await client.CloseAsync(); 
     }
