Message Identifier - x-message-id

im using the header x-message-id in a property in my code and its not being reflected in my event header when I publish it.

public class TurnoverData
{
        public Turnover Turnover { get; set; }
        public string AccountIdToBeActivated { get; set; }
}

public class Turnover
{
        [Header("x-message-id")]
        public string TurnoverId { get; set; }
        public string CreationDateTime { get; set; }
        public string PostingDate { get; set; }
}

I check the source code and found that just if the property is called Id or MessageId the lib retrieve the value and put it in the headers

I’ve thought about the third option too. I though that maybe there would exist another way to do it without having to create a Behavior, but well, i know that reflection is painfull and it carries other issues with that also. Thanks a lot @BEagle1984 for the quickly replies!

Not out of the box. It involves reflection and I kept the logic as lean as possible. The attributes are also being cached and allowing them in a child object would increase the complexity (considering polymorphism as well).

You got many workarounds tho:

1. Move the property to the root
2. Have a calculated property in the root that reflects the value of the child property and decorate that one with the attribute
3. Write a behavior that sets your header (you don’t need to use reflection, just car to your message type and set the header from the property)
4. Replace the HeadersWriterProducerBehavior with a custom implementation

I would go with option 1. If that’s not possible 3 is my second choice.
