C# How to receive a Message from Service Bus Queue and Deadletterqueue with Sequence Number

Question

I want to create my own Monitoring Tool for an Service Bus Queue. To Delete an specific Message in the normal Queue and Deadletterqueue, I need to receive a Message by a Sequence Number. But I can't find a such Method in my Receiver Object. I see a Method to Peek Messages with a Sequence Number, but i can't Complete them and its also not possible on Deatletter Messages. Is there a such Method to get Messages by Sequence Number?

Hi @Tobias Wehrle Thanks for reaching out. This feature is not available as of today, you can only receive messages by sequence number if those are in a "deferred state". For more information refer https://learn.microsoft.com/en-us/azure/service-bus-messaging/message-deferral
One workaround would be to receive all messages from the queue, then send to the DLQ the ones that would like to delete if you're looking forward deleting a specific message inside the DLQ, then you will need to receive them all, and then defer the one that you would like to delete, then use the receive deferred message method to remove it.
